Item 1.01.

Entry into a Material Definitive Agreement.

On April 15, 2026, CareDx, Inc. (the “Company”)

entered into a Purchase Agreement (the “Purchase Agreement”) with Eurobio Scientific S.A. (“Eurobio”), pursuant

to which, and subject to the terms and conditions set forth therein, the Company agreed to sell to Eurobio the shares of CareDx AB, a

wholly-owned Swedish subsidiary of the Company, and certain assets relating to the Company’s kitted laboratory products business

and related software (the “Business”) for $170 million in cash, subject to certain customary adjustments specified in the

Purchase Agreement, including for working capital, cash and indebtedness (the “Transaction”).

Each party’s obligation to consummate the Transaction is subject

to customary closing conditions, including, among other things, (i) subject to certain exceptions, the accuracy of the representations

and warranties of the other party, (ii) performance in all material respects by the other party of its covenants, (iii) the

receipt of a required regulatory approval and (iv) with respect to Eurobio’s obligation, the absence of a material adverse

effect on the Business that is continuing.

The Purchase Agreement contains representations, warranties and covenants

that are customary for a transaction of this nature.

The Purchase Agreement also includes customary termination rights,

including (i) by mutual written consent of Eurobio and the Company, (ii) by either party if a governmental entity permanently

prohibits or makes illegal the consummation of the Transaction, and by Eurobio if a governmental entity imposes certain remedies in connection

with the Transaction that are not required under the Purchase Agreement, (iii) by either party if the Transaction has not been consummated

by October 15, 2026, (iv) by either party, if the other party is in an uncured material breach of its respective

representations and warranties or covenants under the Purchase Agreement such that a closing condition would not be satisfied and (v) by

Eurobio, if there is an uncured material adverse effect on the Business. Pursuant to the Purchase Agreement, the Company and Eurobio will

enter into a transition services agreement at the closing of the Transaction.

The Company is granted the exclusive right to distribute NGS- and PCR-based

post-transplant assays for solid organ or stem cell transplants in the US, Canada and Mexico manufactured by Eurobio, including AlloSeqcfDNA,

AlloSeqHCT, NGStrack, KMRtrack or any other chimerism or cfDNA monitoring product. Eurobio may, however, continue to serve Eurobio’s

existing customers as of the closing of the Transaction with Eurobio’s current existing products. Eurobio retains the exclusive

right in the US, Canada and Mexico to sell the current Company chimerism assay solely to the Company’s existing customers for three

years after the closing of the Transaction, but may not otherwise sell the current Company chimerism assay in North America

The foregoing description of the Purchase Agreement does not purport

to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, which is filed as Exhibit 2.1

to this Current Report on Form 8-K and is incorporated herein by reference.

The Purchase Agreement is filed to provide investors with information

regarding its terms. It is not intended to provide any other factual information about the Company, Eurobio or the Business. The representations,

warranties and covenants contained in the Purchase Agreement were made solely for the benefit of the parties thereto, as of specified

dates, and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the

purposes of allocating contractual risk between the parties instead of establishing these matters as facts. Accordingly, investors should

not rely on the representations, warranties and covenants, or any description thereof, as characterizations of the actual state of facts

or condition of the Company, Eurobio or the Business.

Item 2.02.

On April 15, 2026, the Company issued a press release (the “Press

(b)            Closing

Deliveries. Subject to the satisfaction of the conditions set forth in Article 3 of this Agreement, at or prior to the Closing:

(i)            Purchaser

by means of a wire transfer of immediately available funds to the accounts specified by the Seller and all other items required to be

delivered by Purchaser at Closing to the Seller in accordance with the terms of this Agreement.

Seller. The Parties shall execute and deliver such other Transaction Documents as may be necessary or appropriate to effect the transactions

contemplated by this Agreement.

(iv)            At

2.4            Assumed

Liabilities; Retention by Seller of Excluded Liabilities.

(a)            Upon

the terms and subject to the conditions set forth in this Contribution Agreement, effective as of immediately prior to the Closing, the

Company (but not the Purchaser) shall enter into the Contribution Agreement with the Seller pursuant to which the Company shall agree

to accept, assume, pay, perform, fulfill and discharge when due the Assumed Liabilities, provided, however, that, with

respect solely to any Assigned Contract assigned to the Purchaser (and not to the Company), the Purchaser shall agree to accept, assume,

pay, perform, fulfill and discharge when due the Assumed Liabilities to the extent they are contractual liabilities arising out of any

such Assigned Contract (the “Purchaser Assumed Contractual Liabilities”).

(b)            The

Parties agree that, except for the Assumed Liabilities, the Company shall not (and the Purchaser shall not) assume, pay, perform or discharge

or otherwise have any obligation or liability for, any Liabilities of the Seller or of any Non-Transferred Affiliate (whether now existing

or hereafter arising), and the Seller and its Non-Transferred Affiliates shall retain, and shall be solely responsible and liable for

paying, performing and discharging when due, all such Liabilities of the Seller or such Non-Transferred Affiliates (collectively, the

“Excluded Liabilities”). Any and all incentives, bonuses, retention payments, or other compensation due or promised

to Quark Employees or any other Person by the Seller or by any of the Quark Companies prior to the Closing as a result of or in connection

with the negotiation, execution, Closing, completion or performance of this Agreement or the Transactions and that is not otherwise included

in the calculation of the Net Cash/Net Working Capital set forth in the Purchase Price Adjustments Schedule, shall constitute

an Excluded Liability. The Non-Transferred Employee Commitment shall constitute an Excluded Liability.

2.5            Third

Party Consents.

(a)            Notwithstanding

anything in this Agreement to the contrary, this Agreement shall not constitute an agreement to sell, convey, transfer, assign or deliver

to Purchaser any Purchased Asset, or any claim, right or benefit arising under or resulting from such Purchased Asset, if and for so

long as such transfer or attempted transfer to Purchaser thereof, without the Consent of a third party, under applicable Law or the express

terms of the applicable Assigned Contract, would constitute a breach or other contravention of the rights of such third party, would

be ineffective with respect to any party to an agreement concerning such Purchased Asset, or would in any material way adversely affect

the rights of the Seller or its Affiliates or, upon such transfer, of Purchaser or its Affiliates (including the Quark Companies) with

respect to such Purchased Asset (such assets being collectively referred to herein as “Restricted Assets”). Notwithstanding

anything in this Agreement to the contrary, unless and until any such Consent with respect to any Restricted Asset or Restricted Split

Interest (as defined in Section 2.5(c) below), as appropriate, is obtained or the applicable restriction or impediment

on the sale, assignment and transfer thereof ceases to exist (such occurrence, the “Consent Receipt”), neither such

Restricted Asset nor such Restricted Split Interest shall constitute a Purchased Asset; provided that at no time on or after the

Closing shall any Restricted Assets or Restricted Split Interest for which the Consent Receipt has not occurred constitute Excluded Assets

nor shall any Liability arising out of, or related to, such Restricted Assets or Restricted Split Interest constitute an Excluded Liability

solely by virtue of being a Restricted Asset or Restricted Split Interest, in each case, for purposes of the Seller’s indemnification

obligations under Section 9.1(a)(i)(6). Upon the Consent Receipt, the Seller shall sell, assign, and transfer the relevant

Purchased Asset to which such Consent Receipt relates to Purchaser for no additional consideration.

(b)            From

the Agreement Date until the earlier of (x) the date this Agreement is terminated in accordance with its terms and (y) 12

months following the Closing, each of the Seller and Purchaser shall use, and shall cause their respective controlled Affiliates to use,

commercially reasonable efforts, and shall reasonably cooperate with each other, to obtain or to cause to be obtained any requisite Consent,

substitution, replacement agreement or amendment required to assign, transfer and novate to Purchaser all rights and obligations of the

Seller and its Subsidiaries with respect to the Purchased Assets and the Assumed Liabilities such that, in any case, Purchaser or a designated

Affiliate of Purchaser will have the benefit of such rights and shall be solely responsible for such Assumed Liabilities from and after

the Closing Date. Nothing in this Section 2.5 shall require Purchaser, the Seller or any of their Affiliates to pay any

amount, grant any rights, grant any guarantee or provide any other consideration to any third party or incur additional costs or expenses

in order to obtain any such Consent, except to the extent the other Party consents to make any such payments, or provide such grants

or consideration. In the event that the Seller determines to seek an assignment or novation with respect to any Assigned Contract, Purchaser

shall cooperate with, and shall cause its Affiliates to cooperate with, the Seller and its Affiliates (including, where necessary, entering

into appropriate instruments of assumption) to cause such assignment or novation to be obtained and to have the Seller and its Affiliates

(other than the Quark Companies) released from all liability to third parties with respect to such Assigned Contract to the extent consistent

with the terms of this Agreement. With respect to any Assumed Liabilities for which the Seller, or any Non-Transferred Affiliate, has

any secondary liability to third parties, Purchaser shall provide the Seller with reasonable access and information in order for the

Seller to ascertain continuing compliance by Purchaser and its Affiliates with all material contract terms and conditions applicable

thereto. This Section 2.5(b) does not relate to Shared Contracts which are addressed in Section 2.5(c).

Seller shall use commercially reasonable efforts to separate the rights and obligations under each Shared Contract to the extent related

to the Quark Business and assign and transfer to Purchaser any transferable interest in each such Shared Contract to the extent related

to the Quark Business (a “Split Interest”). If an attempted assignment and transfer of a Split Interest to Purchaser,

without obtaining the Consent of the relevant counterparty to such Shared Contract (the “Relevant Vendor”), would

constitute a breach or other contravention of the terms of the applicable Shared Contract, or would in any material way adversely affect

the rights of the Seller or its Affiliates with respect to such Shared Contract or, upon transfer, of Purchaser or its Affiliates (including

the Quark Companies) with respect to such Split Interest, as applicable (each, a “Restricted Split Interest”), then

the Seller and Purchaser shall reasonably co-operate with each other and shall each use commercially reasonable efforts to either obtain

the requisite Consent from the Relevant Vendor for the assignment and transfer to Purchaser of such Restricted Split Interest prior to

the Closing, or to negotiate and enter into a new agreement with the Relevant Vendor or a replacement vendor or supplier reasonably acceptable

to Purchaser, as mutually agreed by the Seller and Purchaser, for the provision by such vendor of the same or materially similar products,

services or rights to Purchaser or its designated Affiliate following the Closing as are provided to the relevant Quark Company under

such Shared Contract as of the Agreement Date upon terms and conditions to be agreed (or otherwise upon the standard terms and conditions

offered by the relevant vendor or supplier) (a “Replacement Contract”). To the extent such Consent or Replacement

Contract is not obtained prior to the Closing, each of the Seller and Purchaser shall continue to reasonably cooperate with each other

and use commercially reasonable efforts to obtain such Consent or such Replacement Contract, as applicable, until the earlier of (i) the

expiration of 12 months following the Closing Date to obtain such Consents or Replacement Contract, and (ii) the termination, expiration,

lapse or non-renewal of such or expiration of such Shared Contract in accordance with its terms; provided that nothing herein shall require

the Seller or any of its Affiliates to pay any amount, grant any rights, litigate, grant any guarantee, incur any Liability or provide

any other consideration to any relevant vendor or supplier or any other party or incur out-of-pocket costs or expenses in order to obtain

any such Consent or Replacement Contract. Once Consent is obtained for the Transfer of a Restricted Split Interest, such Restricted Split

Interest shall be Transferred to Purchaser (but not before), and such Restricted Split Interest shall be deemed to be a Purchased Asset

for purposes of this Agreement.

(d)            If

any required Consent to assign and transfer a Restricted Asset or a Restricted Split Interest is not obtained on or prior to the Closing

Date (or in the case of a Shared Contract, a Replacement Contract is not in place in lieu of the assignment and transfer of the relevant

Restricted Split Interest), each of the Seller and Purchaser hereby agree to use commercially reasonable efforts to implement such arrangements

(including subleasing, sublicensing or subcontracting) with respect to the underlying rights and obligations related thereto, to the

extent practicable and/or permitted by applicable Law, for Purchaser or one of its Affiliates to perform and discharge (and Purchaser

hereby agrees to perform and discharge) the obligations of the Seller or any applicable Subsidiary of the Seller after the Closing Date

thereunder (to the extent such obligations would otherwise constitute Assumed Liabilities), in exchange for all corresponding rights,

benefits and payments thereunder arising or made after the Closing Date being made available to Purchaser or such Affiliate, and for

Purchaser or one of its Affiliates to assume and timely discharge the obligations of the Seller and its Affiliates with respect thereto

(the “Restricted Asset Obligations”), until the earlier of (i) such time as such Consent to Transfer the applicable

Restricted Asset shall have been obtained (or, in the case of a Restricted Split Interest, a Replacement Contract has been put in place,

as applicable), and (ii) in the case of a Restricted Asset that is a Contract or a Restricted Split Interest, such time as such

Contract or Restricted Split Interest shall have lapsed, terminated, expired or not have been renewed in accordance with its terms. Purchaser

agrees to timely perform and fully discharge, or cause its Subsidiaries to timely perform and fully discharge, the Restricted Asset Obligations,

directly or indirectly, as applicable, and shall indemnify, defend and hold harmless the Seller and its Affiliates for any Losses resulting

from the failure of Purchaser and its Affiliates to perform and discharge such Restricted Asset Obligations; provided, however,

that in relation to a Restricted Split Interest, Purchaser shall be responsible for the Restricted Asset Obligations related to the Restricted

Split Interest only and not the remaining portion of the relevant Shared Contract. Upon Consent Receipt with respect to a particular

Restricted Asset or Restricted Split Interest after the Closing Date, the Parties agree that the obligations related to such Restricted

Asset or Restricted Split Interest will no longer be considered to be Restricted Asset Obligations at such time but will instead be deemed

to be Assumed Liabilities for all purposes of this Agreement.

(e)            Notwithstanding

anything herein to the contrary, the provisions of this Section 2.5 shall not apply to any Consent required from any Governmental

Entity with respect to the consummation of the transactions contemplated hereunder, which Consents shall be governed solely by Section 4.5.

(f)            Notwithstanding

anything in this Agreement to the contrary, the failure to obtain any Consent (other than any required Consent of a Governmental Entity)

for the sale, assignment and transfer of any Purchased Asset to Purchaser or its designated Affiliates, or the failure to transfer any

Restricted Split Interest, or the termination (or receipt of notice of termination thereunder) of any Contract that was intended to be

an Assigned Contract or any Shared Contract, or any facts, circumstances, effects or consequences resulting from any of the foregoing,

shall not, individually or in the aggregate, give rise to any liability whatsoever of the Seller or its Affiliates arising out of or

relating to such failure, or constitute a Material Adverse Effect, or a breach by the Seller of any representation, warranty or covenant

under this Agreement or any of the other Transaction Documents, or a failure of the satisfaction of any condition under this Agreement

or any of the Transaction Documents, including those in Section 3.2 and, subject to the satisfaction or waiver of the conditions

contained in Article 3, the Closing shall occur notwithstanding the foregoing without any adjustment to the Purchase Price

on account thereof.

(g)            In

the event that there are any Contracts for the purchase of products or services from or by the Seller or any of its Affiliates that are

exclusively related to the Quark Business which were not included in the Purchased Assets or the Assumed Liabilities and which were not

specifically excluded from the transfers under this Agreement, but which would have been transferred to Purchaser as part of this Agreement

but for the fact that such Contract was not identified, discovered or located until after the Closing or inadvertently was not assigned

(each, a “Later Discovered Contract”), to the extent permitted under the terms and conditions of such Later Discovered

Contract and under applicable Laws, Purchaser and the Seller agree to cooperate and take such actions as may be necessary to cause such

Later Discovered Contract, or the applicable rights or obligations under such Later Discovered Contract, to be assigned to Purchaser

for no additional consideration and, upon such assignment, such Later Discovered Contract, or the applicable rights or obligations under

such Later Discovered Contract, shall be deemed to be an Assigned Contract hereunder. To the extent that a Later Discovered Contract

constitutes a Restricted Asset, it shall be treated in accordance with the foregoing provisions of this Section 2.5.

not less than thirty (30) days prior to the date on which such Tax Returns are to be filed for the review of Purchaser and Purchaser’s

to the member of the Company Group, (iii) amend any Tax Return of a member of the Company Group for any Pre-Closing Tax Period,

such information (including access to books and records) and assistance relating to Tax periods or portions of Tax periods of any member

of the Company Group ending on or before the Closing Date as is reasonably necessary for the filing of any Tax Return, for the preparation

cause the Company to, at the expense of the Seller, prepare and file all necessary documentation and Tax Returns with respect to such

Transfer Taxes. Seller shall timely reimburse Purchaser or, as applicable, the Company, for payments due under this Section 7.6

case may be, and take any action reasonably requested which does not cause them to incur any unreasonable cost or inconvenience in order

to minimize such Transfer Taxes.

of the Seller for such claims shall be uncapped.

(3)            Any

Loss shall be indemnifiable pursuant to Section 9.1(a) only to the extent (i) that it is not included as a liability

in the Final Net Cash/Net Working Capital Statement or, if it is included as a liability in the Final Net Cash/Net Working Capital Statement

and to the extent it exceeds such liability, then to the extent of such Loss minus the amount of such liability reflected in the Final

Net Cash/Net Working Capital Statement, or (ii) that such Loss is not covered by or not recoverable under the RW Insurance.

(b)            Purchaser’s

Indemnification Obligation.

(i)            Subject

to the other limitations in this Article 9, from and after the Closing, Purchaser agrees to, with respect to (1), (2) and

(3) below, indemnify, and, with respect to (4) below, cause the Company to indemnify, the Seller and any Affiliate of the

Seller and their respective officers, directors, shareholders, employees, agents and representatives (each, a “Seller Indemnitee”)

and hold the Seller Indemnitees harmless from and against any Loss which any such Seller Indemnitee actually pays, incurs or suffers

to the extent arising or resulting from:

(1)            any

Fraud of Purchaser;

(2)            any

representations or warranties made by Purchaser in this Agreement or certificate delivered pursuant to this Agreement being untrue or

incorrect (A) as of the Agreement Date (except to the extent that such representations, warranties, and certifications speak as

of an earlier date, in which case as of such earlier date) or (B) as of the Closing Date as though such representation, warranty,

or certification were made as of the Closing Date (except to the extent that such representations, warranties, and certifications speak

as of an earlier date, in which case as of such earlier date);

(3)            the

Purchaser Assumed Contractual Liabilities, or

(4)            the

Assumed Liabilities.

(ii)            Purchaser,

or, with respect to Section 9.1(b)(i)(4), the Company, will not be liable to indemnify the Seller Indemnitees under Section 9.1(b) unless

a Claim Notice is given by or on behalf of the claiming Seller Indemnitee to Purchaser on or before the relevant Purchaser Survival Date,

it being understood that so long as such Claim Notice is provided on or prior to the relevant Purchaser Survival Date, such Seller Indemnitee’s

right to be indemnified with respect to the matters covered in such Claim Notice shall continue to survive until such matters are resolved.

For purposes of this Agreement, the term “Purchaser Survival Date” shall mean (A) the date that is twenty-four

(24) months after the Closing Date in the case of any claim for indemnification pursuant to Section 9.1(b)(i)(2), and (B) the

date that is thirty days following the expiration of the applicable statute of limitations for the subject matter of any claim for claims

made pursuant to Section 9.1(b)(i)(1), Section 9.1(b)(i)(3) and Section 9.1(b)(i)(4).

(iii)            Except

with respect to indemnification by the Purchaser for any Fraud committed by the Purchaser or the indemnification obligation of the Company

pursuant to Section 9.1(b)(i)(3) and Section 9.1(b)(i)(4), which indemnification obligations shall not

be limited, Purchaser shall be liable to indemnify Seller Indemnitees pursuant to Section 9.1(b) for and shall be

bound by the terms of Section 9.1(b) for an aggregate amount of indemnifiable Losses of up to, but not more than,

the amount of the Purchase Price actually paid by the Purchaser hereunder.

Procedures.

(i)            Notice

of Claim. Any indemnified party making a claim for indemnification pursuant to Sections 9.1(a) or (b) (a

“Claim”) must give the Seller or Purchaser, as the case may be, written notice (a “Claim Notice”)

of any matter which such indemnified party has determined has given rise to, or could reasonably be expected to give rise to, a right

of indemnification under this Article 9, within sixty (60) days of such determination (and in any event promptly after the

indemnified party receives any written notice of any Proceeding or other claim against or involving the indemnified party by a third

party), stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of

this Agreement in respect of which such right of indemnification is claimed or arises; provided, however, that the failure

to provide such notice shall only release the applicable indemnifying party from any of its obligations under this Article 9

to the extent (if any) such indemnifying party is actually materially prejudiced by such failure.

(ii)            Proceedings.

In the event of a Proceeding, the indemnified party shall keep the indemnifying party reasonably informed with respect to such ongoing

Proceeding, and the indemnifying party may provide the indemnified party with guidance and advice with respect to the Proceeding, which

the indemnified party shall reasonably consider to the extent such guidance and advice are reasonable and in the common interests of

the indemnified party and the indemnifying party.

(iii)            Net

Recovery. The amount of any Loss for which indemnification is provided under this Section 9.1 shall be net of the amount

of such Loss (if any) actually recovered by the indemnitee under insurance policies (including, in the case of the Purchaser Indemnitees,

the RW Insurance), net of costs of collection and reasonably estimated costs of premium increases, if any, attributable to insurance

claims with respect to such Loss, and for the avoidance of doubt the indemnitee shall not be obligated to pursue litigation or take other

material steps against the relevant insurance company if the insurance company denies or limits coverage after receiving notice of a

claim (except in the case of the RW Insurance where Purchaser agrees to use reasonable best efforts and to take all actions necessary

to obtain coverage from the insurance company and enforce its rights under the RW Insurance with respect to any such Loss to the extent

such Loss is covered under the RW Insurance).

(iv)            Natera

Settlement. Notwithstanding the foregoing, with respect to the Natera Litigation, the Seller shall not enter into any settlement

that imposes any payment obligation, restriction or license requirement on the Quark Business, the Quark Products or the Quark Software,

or Purchaser or its Affiliates, without Purchaser’s prior written consent (collectively, the “Natera Litigation Matters”).

(v)            RW

Insurance. Notwithstanding anything to the contrary herein, in the event of any Losses incurred by Purchaser that are indemnifiable

by the Seller pursuant to Section 9.1(a)(i)(1) through Section 9.1(a)(i)(3), Purchaser shall first seek

recourse and obtain recourse for any such Losses to the maximum extent of the available coverage therefor under the RW Insurance before

seeking indemnification with respect thereto against the Seller. Purchaser acknowledges and agrees that other than respect to the indemnifiable

matters described in Section 9.1(a)(i)(1) through Section 9.1(a)(i)(3), recourse by the Purchaser to

the RW Insurance constitutes Purchaser’s sole and exclusive remedy for any and all Losses arising out of, resulting from, related

to or in connection with any breach by the Seller of any of its representations and warranties set forth in the Agreement.

(d)            Claims;

Payments. The indemnifying party shall inform the party seeking indemnification not later than ten (10) days after its

receipt of a Claim Notice whether it objects to such Claims and stating in writing its grounds of objection. All indemnification payments

shall be made promptly in accordance with the Claim Notice unless the indemnifying party shall have objected to such Claim. All indemnification

payments made under this Agreement shall be treated for Tax purposes only as an adjustment to the Purchase Price.

(e)            No

Knowledge Effect. Except as expressly provided in this Agreement, the right to indemnification, reimbursement or other remedy pursuant

to or based on this Section 9.1 shall not be affected by any Knowledge existing, acquired or capable of being acquired at

any time, whether before or after the execution and delivery of this Agreement or the Closing Date.

(f)            Following

the Closing, with the exception of remedies based on Fraud by any Party or breach by any Party of any covenants or agreements of such

Party under this Agreement, the indemnification rights set forth in this Section 9.1 shall constitute the sole and exclusive

remedy of a Party for money damages hereunder and shall be in lieu of any other remedies for money damages that may be available to the

indemnified Persons hereunder under any other agreement or pursuant to any statutory or common law with respect to any Losses, Liabilities,

Proceedings, settlements, judgments, awards, penalties, fines, costs or expenses of any kind or nature incurred directly or indirectly

resulting from or arising out of, under or with respect to any of this Agreement, the Quark Business, the Purchased Assets, the Excluded

Assets, the Assumed Liabilities or the Excluded Liabilities (it being understood that nothing in this Section 9.1(f) or

elsewhere in this Agreement shall affect the rights of any Party to specific performance or other similar non-monetary equitable remedies

with respect to the covenants referred to in this Agreement to be performed after the Closing). Each of the Parties hereby waive any

provision of any applicable Law to the extent that it would limit or restrict the agreement contained in this Section 9.1(f).

(g)            Purchaser

and the Seller agree to treat (and cause their respective Affiliates to treat) any payment received by Seller Indemnitees or the Purchaser

Indemnitees, as applicable, pursuant to this Section 9.1 as adjustments to the Purchase Price for all Tax purposes to the

maximum extent permitted by Applicable Law.

9.2            Minimum

Employees.

(a)            Purchaser

shall, or shall cause its Affiliates, to hire and employ the Minimum Quark Employees by providing, no less than 15 days prior to the

Closing Date or any prior date required by applicable Law, an offer of employment to such Quark Employees to become effective on the

Closing Date providing for (i) annual salary or wages in amounts substantially equivalent to the annual salary or wages, as applicable,

paid to such employees by the Seller or any of its Affiliates as of immediately prior to the Closing Date, (ii) cash incentive

compensation opportunities or sales commission arrangements (but excluding any transaction-related incentives, bonus or retention payments,

including without limitation any such payments related to work performed or contributions in connection with the signing, closing or

performance of this Agreement) in amounts substantially equivalent to the cash incentive compensation opportunities or sales commission

arrangements provided to such employees by the Seller or any of its Affiliates as of immediately prior to the Closing Date, (iii) employee

benefits (including retirement benefits, health, vision and dental insurance, life and AD&D insurance, disability insurance, vacation

PTO, sick, holiday, maternity, paternity and other leave) substantially equivalent, in the aggregate, to those provided through the Seller’s

or any of its Affiliates’ employee benefits plans at the time of this Agreement, and (iv) the Post-Closing Severance Benefits,

it being understood that, with respect to the Minimum Quark Employees who are employees of a Quark Company as of immediately prior to

the Closing, such offer may be limited to terms required to be offered to such Minimum Quark Employee as a result of their employer ceasing

to be the Seller or a Non-Transferred Affiliate of the Seller.

(b)            Purchaser

agrees to maintain each Minimum Quark Employee’s employment terms as contemplated above during the 12-month period following the

Closing Date or such longer period as required by any applicable local Laws (the “Continuation Period”), provided

however that Purchaser may terminate any benefits offered to any Minimum Quark Employees during the Continuation Period so long as Purchaser

replaces such terminated benefits with a comparable benefit.

will reasonably consult with and provide the Seller with a reasonable opportunity to review the proposed terms and conditions of the

offers of employment to be made to the Minimum Quark Employees in advance.

(d)            To

the extent that a Minimum Quark Employee is inactive as of the Closing Date due to short-term or long-term disability, workers’

compensation leave, or military leave, the offer of employment referred to in subparagraph (a) above will become effective when

such leave ends and the employee returns to work.

(e)            Purchaser

or any of its Affiliates will credit each Minimum Quark Employee that remains employed with a Quark Company upon the Closing, or that

accepts an offer of employment from Purchaser or an Affiliate of Purchaser, as applicable (each a “Continuing Employee”)

with, and honor and pay for, the amount of accrued and unpaid hours of vacation (to the extent permitted by Law), personal hours or days

earned, sick leave and any other leave required to be credited by Law (together, the “Transferred Leave”) applicable

to such Continuing Employee for the period up to the Closing. The Seller will provide to Purchaser as of the Closing Date a schedule

indicating the type and number of days of Transferred Leave for each Continuing Employee. Purchaser will ensure that such Transferred

Leave is not subject to forfeiture to the same extent not subject to forfeiture under the policies of the Seller and its Affiliates governing

such Transferred Leave prior to the Closing.

(f)            Any

employee that is a Minimum Quark Employee who is not offered continued employment with Purchaser or any of its Affiliates effective upon

the Closing, or who is terminated without cause upon the Closing or at any time during the 12 months following the Closing, shall be

entitled to severance and termination benefits (the “Post-Closing Severance Benefits”) having an aggregate value equal

to the higher of (i) the aggregate value of the severance and benefits described in Schedule 9.2(f) of the Disclosure

Schedule and (ii) the aggregate value of severance or additional termination payments, payments in lieu of notice or other benefits

as may be required by applicable Law, with Purchaser being solely responsible for discharging all costs and obligations related to the

Post-Closing Severance Benefits that become payable to any such Minimum Quark Employee.

(g)            To

the extent permitted or required by applicable Law, Purchaser will cause each employee benefit plan of Purchaser and its Affiliates in

which any Continuing Employee participates that is a health or welfare benefit plan (collectively, “Purchaser Benefit Plans”)

to, if and only if and to the extent that the Purchaser employee benefit plans allows for it without amending the terms thereof, (i) waive

all limitations as to preexisting conditions, exclusions and service conditions or waiting periods or evidence of insurability requirements

with respect to participation and coverage requirements applicable to Continuing Employees, (ii) honor any payments, charges and

expenses of such Continuing Employees (and their eligible dependents) that were applied toward the deductible and out-of-pocket maximums

under the corresponding Seller benefit plan in satisfying any applicable deductibles, out-of-pocket maximums or co-payments under a corresponding

Purchaser Benefit Plan during the same plan year in which such payments, charges and expenses were made, and (iii) with respect

to any medical plan, waive any waiting period limitation or evidence of insurability requirement that would otherwise be applicable to

a Continuing Employee following the Closing Date.

(h)            Purchaser

and its Affiliates will provide credit for each Continuing Employee’s length of service with Seller and its Affiliates for purposes

of eligibility, participation, vesting and benefit accrual under each plan, program, policy or arrangement of Purchaser and its Affiliates

(including severance plans and policies), except that such prior service credit will not be required to the extent that it results in

a duplication of benefits. Seller will provide to Purchaser as of the Closing Date a schedule indicating the length of service of each

Continuing Employee with Seller and its Affiliates through the Closing Date.

(i)            Purchaser

shall have no obligation pursuant to this Section 9.2 with respect to Quark Employees who have been offered employment by

Purchaser or its Affiliates in accordance with the terms of this Section 9.2 but who have not accepted such offer before

the end of the day on the Closing Date.

(j)            Seller

shall be solely responsible for, all restructuring, severance and termination costs (including reasonable attorneys’ fees, payroll

taxes and social security contributions owed by the employer) payable in connection with the termination of any employees or consultants

of the Quark Business not included in the Minimum Quark Employees list who are not hired or retained by the Seller or any of its Non-Transferred

Affiliates, or who are terminated by the Seller, upon the Closing (the “Non-Transferred Employee Commitment”).

(k)            To

the extent that the Company will not hold sufficient Cash in the full amount of the Estimated Employees Severance Budget as of the Closing

Date, the Seller shall, on or prior to the Closing Date, make a cash payment to the Company in an amount sufficient to ensure that the

Company will hold an amount of Cash equal to the Estimated Employees Severance Budget (as defined in the Purchase Price Adjustments Schedule)

as of the Closing Date. The Seller shall cause the Company to retain such Employees Severance Cash in its operating accounts as of the

Closing. Notwithstanding Section 2.4, the Employees Severance Cash shall not be treated as an Excluded Asset.

9.3            Post-Closing

Access to Records and Personnel.

(a)            Exchange

of Information. After the Closing, upon receipt of reasonable notice, each Party agrees to provide, or cause to be provided, to each

other, as soon as reasonably practicable after written request therefor and at the requesting Party’s sole expense, reasonable

access during normal business hours, to the other Party’s employees (without unreasonable disruption of employment) and to any

material books, records, documents, files and correspondence in the possession or under the control of the other Party that the requesting

Party reasonably needs (i) to comply with reporting, disclosure, filing or other requirements imposed on the requesting Party (including

under applicable securities Laws) by a Governmental Entity having jurisdiction over the requesting Party, (ii) for use in any other

judicial, regulatory, administrative or other proceeding, or in order to satisfy Tax, audit, accounting, claims, regulatory, litigation

or other similar requirements, or in order to address any claims, disputes or negotiations with third parties related to the Quark Business,

(iii) in connection with the filing of any Tax Return or election or any amended return or claim for refund, determining a liability

for Taxes or a right to a refund of Taxes or any Tax audit or other Proceeding in respect of Taxes, (iv) to comply with its obligations

under this Agreement, or (v) in connection with any other matter requiring access to any such employees, books, records, documents,

files and correspondence for any reasonable business purpose; provided, however, that no Party shall be required to provide

access to or disclose information where such access or disclosure would violate any Law or agreement, or waive any attorney client or

other similar privilege, and each Party may redact information regarding itself or its Subsidiaries or otherwise not relating to the

Quark Business, and, in the event such provision of information could reasonably be expected to violate any Law or agreement or waive

any attorney client or other similar privilege, the Parties shall take all reasonable measures to permit the compliance with such obligations

in a manner that avoids any such harm or consequence.

(b)            Ownership

of Information. Any information owned by a Party that is provided to a requesting Party pursuant to this Section 9.3

shall be deemed to remain the property of the providing Party. Unless specifically set forth herein, nothing contained in this Agreement

shall be construed as granting or conferring rights of license or otherwise in any such information.

of Liability. No Party shall have any Liability to any other Party in the event that any information exchanged or provided pursuant

to this Section 9.3 is found to be inaccurate or in the event that any information requested from a Party is lost, destroyed

or otherwise unretrievable.

(d)            Other

Agreements Providing for Exchange of Information. The rights and obligations granted under this Section 9.3 are subject

to any specific limitations, qualifications or additional provisions on the sharing, exchange or confidential treatment of information

set forth in this Agreement.

(e)            Confidential

Information. Nothing in this Section 9.3 shall require either Party to violate any agreement with any third parties

regarding the confidentiality of confidential and proprietary information; provided, however, that in the event that either

Party is required under this Section 9.3 to disclose any such information, such Party shall use commercially reasonable

efforts to seek to obtain such third party’s consent to the disclosure of such information and implement requisite procedures to

enable the disclosure of such information.

9.4      Insurance

Matters.       Purchaser acknowledges that the policies and insurance coverage maintained on

behalf of the Quark Business are part of the corporate insurance program maintained by Seller and its Subsidiaries, and such coverage

will not be available or transferred to Purchaser. From and after the Closing Date, the Company Group shall cease to be insured by Seller’s

or its Affiliates’ insurance policies or by any of Seller’s self-insured programs, and Seller and its Affiliates may, to

be effective at the Closing, amend any insurance policies in the manner Seller deems appropriate to give effect to this Section 9.4.

From and after the Closing, Purchaser shall be responsible for securing all insurance it considers appropriate for its operation of the

Quark Business.

9.5            Privileges.

The Parties agree that their respective rights and obligations to maintain, preserve, assert, or waive any attorney-client and work product

privileges belonging to either Party with respect to the Quark Business and the other businesses of Seller (collectively, “Privileges”),

shall be governed by the provisions of this Section 9.5. With respect to matters relating to Seller’s businesses,

the Excluded Assets or the Excluded Liabilities, in each case regardless of whether such matters also relate to the Quark Business, the

Purchased Assets, or the Assumed Liabilities, and with respect to all Business Records, documents, communications, or other information

(collectively, “Information”) of Seller or any Affiliate prepared in connection with this Agreement or the other Transaction

Documents or the transactions contemplated hereby and thereby, Seller shall have sole authority to determine whether to assert or waive

any Privileges, including the right to assert any Privilege against Purchaser and its Affiliates. Purchaser and its Affiliates (including,

as of the Closing Date, the Quark Companies) shall take no action without the prior written consent of Seller that would reasonably be

expected to result in any waiver of any such Privileges of Seller in respect of the Information. After the Closing, Purchaser shall have

sole authority to determine whether to assert or waive any Privileges with respect to matters relating to the Purchased Assets, the Quark

Companies and the Assumed Liabilities (but not including the Excluded Assets, Excluded Liabilities, Information prepared in connection

with this Agreement, the other Transaction Documents or the transactions contemplated hereby and thereby or any other potential transaction

relating to the Quark Business or related sale process, or matters that relate to the businesses of Seller (other than the Quark Business)).

However, Purchaser may not assert any such Privileges of Purchaser related to pre-Closing advice or communications relating to the Quark

Business against Seller and its Affiliates; provided, however, that, to the extent any waiver (or failure to assert such Privilege) would

reasonably be expected to result in such Privilege being waived in connection with any claim by a third party in connection with the

Purchased Assets, the Company Group or the Assumed Liabilities, Seller shall, and shall cause its Subsidiaries to, use reasonable best

efforts to enter into such reasonable arrangements designed to ensure that such Privilege is not otherwise waived with respect to such

third party, including customary joint defense agreements or similar arrangements. Seller and its Affiliates shall take no action after

the Closing without the prior written consent of Purchaser that would reasonably be expected to result in any waiver of any such Privileges

of Purchaser or its Affiliates. The rights and obligations created by this Section 9.5 shall apply to all Information as

to which Seller or its Affiliates or any of the Quark Companies would be entitled to assert or has asserted a Privilege without regard

to the effect, if any, of the transactions contemplated hereby or by the other Transaction Documents (the “Privileged Information”).

Upon receipt by Seller or its Affiliates, or Purchaser and its Affiliates (including, as of the Closing Date, the Company Group), as

the case may be, of any subpoena, discovery or other request from any third party that actually or arguably calls for the production

or disclosure of Privileged Information of the other or if Seller or its Affiliates or Purchaser or its Affiliates (including, as of

the Closing Date, the Company Group), as the case may be, obtains knowledge that any current or former employee of Seller, its Affiliates

or the Company Group or Purchaser or its Affiliates (including, as of the Closing Date, the Company Group), has received any subpoena,

discovery or other request from any third party that actually or arguably calls for the production or disclosure of Privileged Information

of the other Party, such Party shall promptly notify the other of the existence of the request and shall provide the other a reasonable

opportunity to review the Information and to assert any rights it may have under this Section 9.5 or otherwise to prevent

the production or disclosure of Privileged Information. Seller’s transfer of any Information to Purchaser in accordance with this

Agreement and Seller’s agreement to permit Purchaser to obtain Information existing prior to the Closing are made in reliance on

the Parties’ respective agreements, as set forth in this Section 9.5, to maintain the confidentiality of such Information

and to take the steps provided herein for the preservation of all Privileges that may belong to or be asserted by Seller or Purchaser,

as the case may be. The access to other Information being granted pursuant to Section 9.4, Section 9.12, Section 9.13

and Section 10.11, and the disclosure to Purchaser and Seller of Privileged Information relating to the Quark Business or

the other businesses of Seller pursuant to this Agreement in connection with the transactions contemplated hereby or any other Transaction

Document shall not be asserted by Seller or Purchaser to constitute, or otherwise be deemed, a waiver of any Privilege that has been

or may be asserted under this Section 9.5 or otherwise.

9.6            Indemnification

of Directors and Officers.

(a)            If

the Closing occurs, Purchaser shall and shall cause the Quark Companies to take any necessary actions to provide that all rights to indemnification

and all limitations on liability relating to the Quark Companies existing in favor of the Business Indemnitees as provided in the D&O

Indemnity Arrangements shall survive the consummation of the transactions contemplated hereby and continue in full force and effect and

shall be honored by the Quark Companies after the Closing. As used herein, (x) the “Business Indemnitees” means

individuals who at or prior to the Closing were current or former officers, directors, individual managers or employees of the Quark

Companies (or the predecessors of the Quark Companies) relating to service in such capacities prior to the Closing and (y) the

“D&O Indemnity Arrangements” means (i) the organizational or charter documents of each of the Quark Companies

in effect on the Agreement Date, and (ii) any agreement providing for indemnification by any Quark Company of any of the Business

Indemnitees in effect on the Agreement Date to which any Quark Company is a party.

(b)            In

the event that the any Quark Company or Purchaser or any of their respective successors or assigns (i) consolidates with or merges

into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers

or conveys all or a majority of its properties and assets to any Person, then, and in each such case, proper provision shall be made

so that the successors and assigns of such Quark Company or Purchaser, as the case may be, shall succeed to the obligations set forth

in this Section 9.6.

shall procure that, at the next annual general meeting of the Company following the Closing, the directors and managing directors of

the Company resigning from such positions in connection with the Closing, to the extent legally permissible, shall be granted discharge

from any Liability to the Company with respect to their service as members of the board of directors or as managing directors of the

Company; provided, however, that no such discharge shall be granted if it is contrary to the recommendation of the auditor

of the Company.

(d)            The

obligations of Purchaser and the Quark Companies under this Section 9.6 shall not be terminated or modified in such a manner

as to adversely affect any indemnitee to whom this Section 9.6 applies without the express written consent of such affected

indemnitee (it being expressly agreed that the Business Indemnitees to whom this Section 9.6 applies shall be third party

beneficiaries of and entitled to directly enforce the provisions of this Section 9.6).

9.7            Further

Assurances.

(a)            In

addition to the actions specifically provided for elsewhere in this Agreement, each of the Parties will cooperate with each other and

use its commercially reasonable efforts, prior to, at and after the Closing Date, to take, or cause to be taken, all actions, and to

do, or cause to be done, all things reasonably necessary or appropriate on its part to consummate and make effective, in the most expeditious

manner practicable, the Transactions, including the execution and delivery of such other instruments, certificates, agreements and other

documents and the performance of such other actions as may be necessary or reasonably desirable to consummate and implement expeditiously

the Transactions; provided that all such actions are in accordance with applicable Law. Notwithstanding the foregoing, from time

to time, whether at or after the Closing, Seller and its Affiliates (as appropriate) will execute and deliver such further instruments,

certificates, agreements and other documents and perform such other actions, at Purchaser’s sole expense and subject to Section 2.5,

as Purchaser may reasonably require to more effectively Transfer to Purchaser any of the Purchased Assets and Purchaser will execute

and deliver such instruments, certificates, agreements and other documents and perform such other actions, at Seller’s sole expense,

as Seller or its Affiliates may reasonably require to more effectively transfer the Assumed Liabilities to Purchaser.

(b)            Delivery

of Business Records and Data Migration. The Parties shall develop and implement a plan for the migration and transfer of the Business

Records held by Seller and its Affiliates (other than the Company Group) as of the Closing to Purchaser or the Company Group in connection

with the Closing. Notwithstanding anything herein to the contrary, it is understood and agreed that Seller shall only be obligated to

use reasonable efforts to locate and deliver the Business Records to the Company Group by the Closing and shall, following the Closing,

deliver any such Business Records to the Company Group that, within one year after the Closing, are identified by either the Seller or

Purchaser as still being in the Seller’s possession following the Closing (with such identification to have sufficient specificity

as to location of the relevant item so as to enable the Seller to readily find, obtain and transfer same). Except as expressly provided

in this paragraph, the Seller shall have no liability whatsoever under this Agreement or otherwise for any failure to transfer or deliver

the Business Records to Purchaser or the Company Group either at or following the Closing.

9.8      Shared

Services      . Except as expressly provided for in the Transition

Services Agreement, Purchaser acknowledges and agrees that, effective as of the Closing Date, (a) all Shared Services provided

to the Quark Business shall cease, and (b) Seller or its Affiliates shall have no further obligation to provide any such Shared

Services with respect to the Quark Business.

9.9            Existing

Intercompany Agreements and Arrangements.

(a)            Except

as set forth in Section 9.9(b), Purchaser acknowledges and agrees that all Intercompany Agreements, and all rights and obligations

of the Quark Business or the Company Group under such Intercompany Agreements, will be terminated, discharged, cancelled or extinguished

at or prior to the Closing. No such Intercompany Agreement or any arrangement, commitment or understanding relating thereto (including

any provision thereof that purports to survive termination) shall be of any further force or effect after the Closing.

(b)            The

provisions of Section 9.9(a) shall not apply to this Agreement, the other Transaction Documents and each other agreement,

arrangement, commitment or understanding expressly contemplated by this Agreement or any other Transaction Document to be entered into

or continued after the Closing (including Transaction Documents to be effective upon the Closing).

9.10            Pending

Litigation. Seller shall be responsible for defending and resolving, at its own cost and expense, the Natera Litigation Matters.

To the extent that any Natera Litigation Matter is not resolved or settled prior to the Closing, Seller and its Affiliates shall continue

to conduct, direct, control and be responsible for the defense, settlement and/or other resolution of such Natera Litigation Matter following

the Closing, and in such regard, shall have the right to control and direct in Seller’s sole discretion any and all investigation,

preparation, response, defense, resolution, remediation and any other action or non-action in connection therewith. Purchaser shall reasonably

co-operate with, and provide any assistance reasonably requested by, Seller and its Affiliates, including access to personnel and facilities

and access to and copies of documentation, records and information (including for purposes of deposition and trial testimony and preparation),

in connection with the defense and settlement of a Natera Litigation Matter following the Closing; provided that such access shall be

conducted at reasonable times and under reasonable circumstances and shall not unreasonably interfere with or disrupt the business operations

of Purchaser. Purchaser shall not, and shall cause its Affiliates not to, (a) take any action that would adversely affect, interfere

with or limit the ability of Seller to defend or resolve a Natera Litigation Matter in any respect, and (b) file any papers, or

consent to the entry of any judgment, or enter into any settlement, with respect to a Natera Litigation Matter, without the prior written

consent of Seller. Seller shall not settle a Natera Litigation Matter in any manner that would involve the admission of any Liability

by Purchaser or any entity of the Quark Entities or that would result in any liability, obligation or restriction for or imposed on Purchaser

or any of its Affiliates.

9.11            Non-Solicitation

of Continuing Employees. For a period of 24 months following the Closing Date, the Seller shall not, and shall cause its Affiliates

not to, directly or indirectly, solicit for employment, or engagement as an independent contractor, any Continuing Employee; provided,

however, that nothing in this paragraph shall prohibit (a) general solicitations by the Seller or any of its Affiliates for employment

not specifically directed at any of the Continuing Employees (including, without limitation, advertisements in newspapers, trade publications,

or on websites or job boards), (b) the Seller or any of its Affiliates from soliciting or hiring any Continuing Employee (i) whose

employment with Purchaser or its Affiliates has been terminated by Purchaser or its Affiliates on or following the Closing, or (ii) that

has not been employed by Purchaser or its Affiliates for at least six months prior to such solicitation, or (c) the Seller or its

Affiliates from soliciting or hiring any Continuing Employee who independently contacts the Seller or any of its Affiliates without any

solicitation by the Seller or its Affiliates in violation of this Section 9.11. For the avoidance of doubt, this restriction

shall not apply to any employee or consultant working for the Quark Business prior to the Closing who is not a Continuing Employee.

9.12            RW

Insurance Policy. At the Closing, or promptly (and in any event within two Business Days) thereafter, Purchaser shall deliver to

the Seller a copy of the bound policy for the RW Insurance. Purchaser hereby acknowledges and agrees that any failure of the Purchaser

to obtain the RW Insurance shall be entirely the risk of Purchaser and shall not have any effect on the obligations of Purchaser hereunder

to consummate the Transactions or expand or otherwise modify any of the rights of Purchaser, or affect any of the limitations on such

rights hereunder, to seek recourse against the Seller hereunder for any matter.

9.13            Mutual

Assistance. The Parties to this Agreement agree that they will mutually cooperate in the expeditious filing of all notices, reports

and other filings with any Governmental Entity required to be submitted jointly by any of the Parties to this Agreement in connection

with the execution and delivery of this Agreement, the other agreements contemplated by this Agreement and the consummation of the transactions

contemplated by this Agreement or thereby. Subsequent to the Closing, each of the Parties to this Agreement, at their own cost, will

assist each other (including by the retention of records and the provision of access to relevant records) in the preparation of their

respective Tax Returns and the filing and execution of Tax elections, if required, as well as in the defense of any audits or litigation

that may ensue as a result of the filing thereof, to the extent that such assistance is reasonably requested.

9.14            Confidentiality.

Before, on and after the Closing Date, Purchaser and the Seller will use their respective best efforts to maintain the confidentiality

of this Agreement and the transactions contemplated by this Agreement, and, except as strictly required by applicable Law, regulation

or legal process, shall not, without prior consent of the other party, disclose the contents or existence of this Agreement or the transactions

contemplated by this Agreement (the “Confidential Information”), provided, however, that (a) Purchaser or Seller

may issue such press release or statement or make such other disclosures as such Party may reasonably determine is necessary to comply

with applicable Law or the rules and regulations of any national securities exchange, (b) the Parties may issue any press

release or make a public announcement (including to analysts or investors) to the extent that such release or announcement only contains

information previously publicly disclosed in accordance with this Section 9.14 or is otherwise consistent in all material

respects with previous statements made jointly by Purchaser and Seller or with the permission of the other Party, and (c) Seller

may disclose any information concerning the Transactions which it deems appropriate in its reasonable judgment, in light of its status

as a publicly owned company, including to securities analysts and institutional investors and in press interviews. No press releases,

announcements to the employees, customers or suppliers of the Company Group or other releases of information related to this Agreement

or the transactions contemplated by this Agreement will be issued or released by the Seller or the Company Group without the prior written

consent of Purchaser.

9.15            Expenses.

Except as otherwise set forth in this Agreement, each Party to this Agreement shall be solely responsible for and shall bear all of its

own costs and expenses incident to its obligations under and in respect of this Agreement and the transactions contemplated by this Agreement,

including, but not limited to, any such costs and expenses incurred by any Party in connection with the negotiation, preparation and

performance of and compliance with the terms of this Agreement (including, without limitation, the fees and expenses of legal counsel,

accountants, investment bankers or other representatives and consultants), regardless of whether the transactions contemplated by this

Agreement are consummated.

9.16            Disputes;

Arbitration Procedure.

(a)            Each

of the Parties to this Agreement agrees that it will attempt to settle any dispute, claim or controversy arising out of this Agreement

through good faith negotiations.

(b)            Any

dispute, claim or controversy that cannot be resolved by the Parties through good faith negotiations within thirty (30) Business Days

of the notification to the other Party of the commencement of the dispute resolution procedures of this Section 9.16 will

then, upon the written request of any Party to this Agreement, be resolved by binding arbitration conducted in English in Manhattan,

New York, NY, United States of America, in accordance with the then effective Rules of Arbitration of the International Chamber

of Commerce by a panel of three arbitrators. Such arbitrators shall be mutually agreeable to the Parties. If the Parties cannot mutually

agree upon the selection of the arbitrators, the arbitrators shall be selected in accordance with the then effective Rules of Arbitration

of the International Chamber of Commerce. Notwithstanding the foregoing, if the aggregate amount in dispute (inclusive of claims, counterclaims

and set-off defenses) does not exceed $5,000,000, the dispute shall be heard by a sole arbitrator selected in accordance with the then

effective Rules of Arbitration of the International Chamber of Commerce, unless the parties agree otherwise in writing. All arbitrators

shall be fluent in English and experienced in the negotiation and interpretation of complex cross-border share purchase agreements governed

by New York law. To the extent not governed by such rules, such arbitrators shall be directed by the Parties to set a schedule for determination

of such dispute, claim or controversy that is reasonable under the circumstances. Such arbitrators shall be directed by the Parties to

determine the dispute in accordance with this Agreement. The International Chamber of Commerce Expedited Procedure Provisions shall not

apply. The International Chamber of Commerce Emergency Arbitrator Provisions shall apply. The arbitration tribunal shall have the power

to grant any interim, conservatory or emergency measures it deems appropriate, including injunctive relief and orders for the preservation

of evidence or assets. Application to any court for such measures shall not be deemed incompatible with or a waiver of these arbitration

provisions. The Parties, their Representatives and the tribunal shall maintain the confidentiality of the arbitration proceedings, all

materials submitted or exchanged in connection with the arbitration, and any award, except to the extent disclosure is required by applicable

Law or for the purposes of enforcement of an award. The award of the tribunal shall be final and binding on the parties. Judgment upon

the award may be entered by any court of competent jurisdiction. The parties waive, to the fullest extent permitted by Applicable Law,

any right to appeal or to seek review of the award by any court or tribunal.

contained in this Section 9.16 shall prevent any Party to this Agreement from resorting to judicial process if injunctive

or other equitable relief from a court is necessary to prevent injury to such Party or its Affiliates and if such Party demonstrates

that the International Chamber of Commerce Emergency Arbitrator Provisions are unfit to prevent such injury. The use of arbitration procedures

will not be construed under the doctrine of laches, waiver or estoppel to affect adversely the rights of any Party to this Agreement

to assert any claim or defense other than as expressly set forth in this Agreement; the prevailing Party in the final, non-appealable

determination of any dispute, claim or controversy brought in arbitration, court or other judicial process in accordance with this Agreement

shall be reimbursed fully and promptly by the non-prevailing Party for attorneys fees and costs, arbitration fees, court costs and other

reasonable costs and expenses incurred by such prevailing Party in connection with the resolution of such dispute, claim or controversy.

9.17            Non-Compete.

Subject to the exceptions in clauses (a) – (d) below, for a period of five years following the Closing Date, the Seller

shall not, and shall procure that the Seller’s controlled Affiliates do not, develop, produce, market or sell a HLA Kit or PTS

Kit (as each term is defined below) (the “Restricted Products”) in any country or territory in the world (the “Non-Compete”).

The Non-Compete shall not apply in each of the following cases: (a) the exercise by Seller or any of its Affiliates of any of Seller’s

rights set forth in the Distribution Agreement shall not be deemed restricted in any respect by the Non-Compete, (b) Seller’s

and its Affiliates’ development, production, marketing, sale, provision or other commercialization of any products or services

that are not a HLA Kit or PTS Kit, including without limitation all laboratory testing services, shall not be restricted in any respect

by the Non-Compete; (c) the Non-Compete shall not apply to any products or services of any entity or business acquired by Seller

or any of its Affiliates on or after the Closing Date, provided that if Seller acquires an entity or business that is commercializing

a HLA Kit or PTS Kit, then promptly following the consummation of such acquisition Seller and Purchaser shall negotiate in good faith

and enter into an exclusive distribution agreement where the Purchaser or its Affiliate shall be appointed as the exclusive distributor

of such acquired HLA Kit and/or PTS Kit in all countries and territories outside of Canada, U.S. and Mexico, and (d) the Non-Compete

shall not apply to any entity or person that acquires Seller or any of Seller’s Affiliates or to any Affiliates of such acquiring

person (other than Seller and Seller’s controlled Affiliates upon consummation of such acquisition).  As used herein, “HLA

Kit” means an in vitro diagnostic or RUO kit or kit-associated software consisting of a pre-packaged set of reagents

or code to allow a user to conduct genotyping using DNA, RNA or other genomic data for purposes of typing of Human Leukocyte Antigens,

and for clarity the kit may be NGS Amplicon based, Hybrid capture based, whole genome cfDNA sequencing based, SNP based and Long read

sequencing based; and “PTS Kit” means an in vitro diagnostic or RUO kit or analysis kit-associated software

consisting of a pre-packaged set of reagents or code to allow a user to conduct post organ or stem cell transplant surveillance which

consists of genomic DNA (also known as chimerism) or donor derived cell free DNA measurements, and for clarity the kit may use without

limitation NGS Amplicon based, Hybrid capture based, whole genome cfDNA sequencing based, SNP based, PCR-based and Long read sequencing

based.

9.18            No

Inconsistent Action. The Seller shall not at any time grant any power of attorney to any person in any way related to or covering

any member of the Company Group or in any way contrary and/or inconsistent with this Agreement or any Transaction Document.

9.19           Transition

Services Scoping. Within 15 Business Days following the date of this Agreement, the Parties shall use reasonable best efforts to

finalize the full scope of the services provided under the Transition Services Agreement, including completion milestones, budget, cap

and allocation of resources.

9. 20          Equity

Commitment Letters. Immediately upon notice by the Seller to Purchaser, Purchaser shall take all actions necessary to fully enforce

its rights under, and exercise all available remedies, under the terms of each of the Equity Commitment Letters to require the Sponsors

to comply with their obligations thereunder and fund their respective equity commitments to Purchaser, including causing EB Development

SAS to enforce all of its rights to obtain loan funding under the Debt Commitment Letter (as defined in the Equity Commitment Letter

between EB Development SAS and Purchaser) and the Facility Agreement (as defined in the Equity Commitment Letter between EB Development

SAS and Purchaser).

10.3            Assignment.

This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of each of the Parties to this Agreement

and their respective successors and permitted assigns. Neither this Agreement nor any rights, benefits or obligations set forth in this

Agreement may be assigned by any of the Parties to this Agreement, provided, however, that Purchaser may assign any or

all of its rights and obligations, or parts thereof, hereunder to one or more of its Affiliates (with notice thereof to be given promptly

to the Seller) it being understood that notwithstanding any such assignment, Purchaser shall remain fully obligated with respect to all

obligations of Purchaser under this Agreement.

10.4            Severability.

Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable

Law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable Law, such provision will be ineffective

only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions

of this Agreement.

10.5            Captions.

The captions used in this Agreement are for convenience of reference only and do not constitute a part of this Agreement and shall not

be deemed to limit, characterize or in any way affect any provision of this Agreement, and all provisions of this Agreement shall be

enforced and construed as if no caption had been used in this Agreement.

10.6            No

Third-Party Beneficiaries. Except as otherwise expressly set forth in this Agreement, nothing in this Agreement expressed or implied

is intended or shall be construed to confer upon or give to any Person, other than the Parties to this Agreement and their respective

permitted successors and assigns, any rights or remedies under or by reason of this Agreement, such third parties specifically including,

without limitation, employees or creditors of the Seller except that, notwithstanding the foregoing, the Business Indemnitees shall be

express third party beneficiaries of and shall be entitled to rely upon and enforce the provisions of Section 9.6 hereof.

10.7            Complete

Agreement. This Agreement and the Transaction Documents contain the complete agreement between the Parties and supersede any prior

understandings, agreements or representations by or between the Parties, written or oral, which may have related to the subject matter

hereof in any way.

10.8            Counterparts.

This Agreement may be executed in one or more counterparts, any one of which may be by electronic copy in .pdf format or via a reputable

electronic signature platform such as Docusign, all of which taken together shall constitute one and the same instrument.

10.9            Bulk

Transfers. Purchaser waives compliance by the Seller and its Affiliates with the provisions of all applicable Laws relating to bulk

transfers in connection with the transfer of the Purchased Assets and the consummation of the Transactions.

10.10            Governing

Law. This Agreement shall be governed by and construed in accordance with the domestic laws of the State of New York, without giving

effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that

would cause the application of the laws of any jurisdiction other than the State of New York.

10.11            Specific

Performance. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions

of this Agreement were not performed in accordance with its specified terms or were otherwise breached, and that monetary damages, even

if available, would not be an adequate remedy therefor. Accordingly, the parties acknowledge and agree that the parties hereto shall

be entitled to an injunction or injunctions, specific performance, or any other appropriate form of equitable relief, to prevent breaches

of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement in any court, without proof

of damages or otherwise (and each party hereto hereby waives any requirement for the securing or posting of any bond or any other security

in connection with any such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The right

to specific enforcement shall include the right of the Seller to cause Purchaser to cause the Transactions to be consummated on the terms

and subject to the conditions set forth in this Agreement. The parties hereto further agree not to assert that a remedy of specific enforcement

is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that any remedy of monetary damages would provide

an adequate remedy. Each of the parties hereto acknowledges and agrees that the right of specific enforcement is an integral part of

the Transactions and without such right, none of the parties hereto would have entered into this Agreement. If, prior to the Drop Dead

Date, any party hereto brings any Proceeding, in each case, in accordance with this Agreement, to enforce specifically the performance

of the terms and provisions hereof by any other party hereto, the Drop Dead Date shall automatically be extended by (i) the amount

of time during which such Proceeding is pending plus 10 Business Days, or (ii) such time period established by the court presiding

over such Proceeding, as the case may be.

10.12            Construction.

When a reference is made in this Agreement to Articles, Sections, Schedules or Exhibits, such reference shall be to an Article or

Section of, or a Schedule or Exhibit to this Agreement unless otherwise indicated. The words “include,” “includes”

and “including” when used herein shall be deemed in each case to be followed by the words “without limitation.”

Where a reference is made to a Contract, schedule, exhibit, instrument or law, such reference is to such Contract, schedule, exhibit,

instrument or law as amended, modified or supplemented, including comparable successor law and references to all attachments thereto

and instruments incorporated therein. Any document or item shall be deemed “delivered”, “provided” or “made

available” to Purchaser and its Representatives if such document or item is included in the Project Quark electronic data room

hosted by Intralinks no later than 11:59 p.m. Pacific time on the date which is one Business Day prior to the date hereof. Unless

the context of this Agreement otherwise requires: (i) words of any gender include each other gender, (ii) words using the

singular or plural number also include the plural or singular number, respectively, (iii) the terms “hereof,” “herein,”

“hereunder” and derivative or similar words refer to this entire Agreement, (iv) references to clauses without a cross-reference

to a Section or subsection are references to clauses within the same Section or, if more specific, subsection, (v) references

to any Person include the successors and permitted assigns of that Person, (vi) references from or through any date shall mean,

unless otherwise specified, from and including or through and including, respectively, (vii) the word “will” shall

have the same meaning and effect as the word “shall”, (viii) the word “or” shall not be exclusive and (ix) references

to “written” or “in writing” include in electronic form. The word “extent” in the phrase “to

the extent” means the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.”

Unless indicated otherwise, (i) any action required to be taken by or on a day or Business Day may be taken until 11:59 p.m. Pacific

time on such day or Business Day, and whenever any action must be taken under this Agreement on or by a day that is not a Business Day,

then that action may be validly taken on or by the next day that is a Business Day, (ii) all references to “days” shall

be to calendar days unless otherwise indicated as a “Business Day” (iii) all days, Business Days, times and time periods

contemplated by this Agreement will be determined by reference to Pacific time, and (iv) the measure of a period of one month or

one year for purposes of this Agreement shall be that date of the following month or year corresponding to the starting date; provided,

that, if no corresponding date exists, the measure shall be that date of the following month or year corresponding to the next day following

the starting date. Unless indicated otherwise, all mathematical calculations contemplated by this Agreement shall be rounded to the tenth

decimal place, except in respect of payments, which shall be rounded down to the nearest whole United States cent. All references to

“$” and dollars will be deemed to refer to United States currency unless otherwise specifically provided. Accounting terms

which are not otherwise defined in this Agreement have the meanings given to them under GAAP; provided, that to the extent that the definition

of an accounting term defined in this Agreement is inconsistent with the meaning of such term under GAAP, the definition set forth in

this Agreement will control. The phrase “date hereof” means the date of this Agreement without giving effect to any amendments,

modifications or supplements hereto. Each of the representations and warranties shall have independent significance. If any Party has

breached any representation, warranty, covenant or agreement contained in this Agreement in any respect, the fact that there exists another

representation, warranty, covenant or agreement relating to the same subject matter (regardless of the relative levels of specificity)

which such Party has not breached shall not detract from or mitigate the fact that such Party is in breach of the first representation,

warranty, covenant or agreement. The principles of interpretation set forth in this Section 10.12 shall apply equally to

all Transaction Documents, unless a Transaction Document provides otherwise by its terms.

10.13            Other

Matters. Each Party has participated in the drafting of this Agreement and the documents executed or delivered pursuant to or in

connection with this Agreement, all of which each Party acknowledges are the result of extensive negotiations among the Parties. Consequently,

this Agreement and the documents executed or delivered pursuant to or in connection with this Agreement shall be interpreted without

reference to any rule or precept of law that states that any ambiguity or term in a document be construed against the drafter.

10.14            WAIVER

OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM

(WHETHER BASED ON CONTRACT, TORT, EQUITY OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY HERETO

IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

(b) CareDx’s donor-derived cell-free DNA count products, which are also known as “absolute quantification” products

of cell-free DNA or (c) any other future CareDx products developed after the Effective Date. For the avoidance of doubt, for purposes

ANY THEORY OF LIABILITY, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), PRODUCTS LIABILITY, OR OTHERWISE. THE PROVISIONS OF

THIS SECTION SHALL APPLY EVEN IF A PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND NOTWITHSTANDING ANY FAILURE OF

ESSENTIAL PURPOSE OF ANY LIMITED REMEDY. CAREDX’S MAXIMUM LIABILITY UNDER THIS AGREEMENT IS LIMITED TO $100.

actions and causes of action, threatened or actual, which any one of the CareDx Indemnitees may suffer or incur in each case to the extent

arising directly or indirectly out of or in connection with any claim, action, or proceeding made or brought against such CareDx Indemnitee

by a third party which arises from the use of the Referenced Data by Eurobio or Eurobio’s negligence or willful misconduct. This

Section shall survive any expiration or termination of this Agreement.

5. General.

No amendment or modification

hereof shall be valid or binding upon the parties unless made in writing and signed by the duly authorized representatives of both parties.

In the event that any provision or provisions of this Agreement shall be held to be unenforceable, the parties shall renegotiate those

provisions in good faith to be valid, enforceable substitute provisions which provisions shall reflect as closely as possible the intent

of the original provisions of this Agreement. Eurobio may not assign this Agreement without the express prior written consent of CareDx,

except for an assignment in connection with a merger, acquisition, asset sale or other change of control. This Agreement shall be construed

and enforced in accordance with the laws of the State of New York, U.S.A., without regard to the conflicts of law principles thereof.

The waiver by either party of a breach of any provision of this Agreement or the failure by either party to exercise any right hereunder

shall not operate or be construed as a waiver of any subsequent breach of that right or as a waiver of any other right. This Agreement

shall not be deemed to give any right or remedy to any third party unless that right or remedy is specifically agreed upon by both parties

in writing to that third party. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of

which shall constitute the same instrument.

parties hereto have caused this Agreement to be duly executed, effective as of the Effective Date.

into between Eurobio Scientific SA (“Eurobio”) and CareDx, Inc. (“CareDx”).

WHEREAS, the parties hereto

to Eurobio together with all rights and obligations under that certain License and Commercialization Agreement between CareDx and Illumina, Inc.

dated May 4, 2018 as amended (“Illumina” and the “Illumina Agreement”);

NOW THEREFORE, the parties

hereby agree as follows:

1.            APPOINTMENT

AND SCOPE

1.1            Appointment.

Eurobio hereby appoints CareDx as its perpetual, exclusive distributor of the products described in Exhibit A (the “Products”)

in the United States (and its territories and possessions), Canada and Mexico (collectively, the “Territory”). CareDx

hereby accepts such appointment. In addition, Eurobio hereby grants to CareDx an exclusive, perpetual license to sell, offer for sale

and import the Products in the Territory. In the case Eurobio sells, transfers or assigns its rights in and to any of the Products (including

in the case of an acquisition of Eurobio as a company), the foregoing appointment and license grant shall run with the Products and Eurobio

shall ensure that the acquirer agrees to honor this appointment and license grant; provided, that, in the event of any sale, transfer

or assignment, the scope of the licenses and distribution rights under this Agreement shall be limited to those Products of Eurobio and

its Affiliates that are existing immediately prior to the consummation of such sale, transfer or assignment and shall not extend to the

other products and services of the acquiring entity.

1.2            Exclusivity.

For the purposes of Section 1.1 above, the term “exclusive” means that (a) Eurobio undertakes to not,

directly or indirectly, grant, or consent to grant, any rights to make, use, sell, offer for sale or import the Products in the Territory,

(b) Eurobio will not market, promote, sell or offer for sale the Product to any third party within the Territory, or located outside

the Territory but with rights to re-sell within the Territory, and (c) Eurobio or its Affiliates will not themselves, and will

not allow or knowingly tolerate any third party to, promote, market, sell, offer for sale or import the Product in the Territory. In

particular, Eurobio will neither solicit nor have solicited customers for the Products in the Territory, conduct marketing activity in

the Territory for the Products nor allow any third party to do so. As used herein “Affiliates” means, with respect

to an entity, any other entity that directly or indirectly controls, is controlled by, or is under common control with, such entity;

where an entity shall be regarded as in control of another entity if it owns, or directly or indirectly controls, at least fifty percent

(50%) of the voting equity interest of the other entity, or if it directly or indirectly possesses the power to direct or cause the direction

of the management and policies of the other entity by any means whatsoever.

1.3            Limited

Exceptions to Exclusivity.

(a)            Notwithstanding

the exclusivity under Section 1.1 above, Eurobio or any of its Affiliates may continue to sell to Eurobio Existing Customers (as

defined below) Products that Eurobio had previously sold to such Eurobio Existing Customers prior to the Effective Date; provided that

for the avoidance of doubt, Eurobio and its Affiliates shall not have the right to sell the CareDx AlloSeq HCT or AlloSeq cfDNA products

to any customer located in the Territory other than to the CareDx Existing Customers as provided for in Section 1.3(b) below.

(b)            Eurobio

or any of its Affiliates will have the exclusive right, in the Territory, to sell the CareDx AlloSeq HCT chimerism and AlloSeq cfDNA

products, as it exists as of the Effective Date, solely to the CareDx Existing Customers for thirty-six (36) months after the Effective

Date, subject to extension of such term as approved in writing by CareDx in its sole discretion.

used herein, the “CareDx Existing Customers” means those CareDx customers located in the Territory that exist as of

the Effective Date and are set forth on Exhibit B, provided that CareDx may add to such customer list by providing written notice

to Eurobio; and the “Eurobio Existing Customers” means those Eurobio customers located in the Territory that exist

as of the Effective Date and are set forth on Exhibit C.

1.4            Research

Institutions.

(a)            Eurobio

acknowledges that prior to the Effective Date, CareDx has been supplying AlloSeq cfDNA and AlloSeq HCT (“Legacy Products”)

to those academic and research institutions listed on Exhibit D (the “Research Institutions”) for the conduct

of research programs. Some of the Research Institutions are located outside of the Territory. Notwithstanding the foregoing in Sections 1.1

- 1.3, CareDx shall have the right to continue to provide the Legacy Products to the Research Institutions to continue to conduct such

research programs, and the pricing for such Legacy Products shall be Eurobio’s fully burdened cost to manufacture the Products,

with no mark up (i.e. the ‘at cost’ pricing). CareDx shall only sell to the Research Institutions for purposes of conduct

such research programs, and shall contractually prohibit use by Research Institutions for other purposes, but CareDx shall not be liable

if the Research Institutions use the Products outside of such research programs. CareDx will provide Eurobio with access to all data

and research results related to all Legacy Products, to the extent the Research Institutions have provided such data and research to

CareDx.

1.5            Compliance

with Terms of Illumina Agreement. CareDx hereby acknowledges that it has received, reviewed and is in possession of the Illumina

Agreement, including, without limitation, those provisions relating to Illumina Intellectual Property, Confidential Information, anti-bribery,

anti-corruption, ethics and compliance. To the extent that they may be applicable, CareDx agrees to comply with, and to cause its representatives

to comply with, all applicable terms and conditions of the Illumina Agreement as if CareDx were a direct party thereto, to the extent

applicable to CareDx’s performance hereunder. In the event of any conflict, inconsistency or gap between the terms of this Agreement

and the Illumina Agreement, the terms that are more protective of the rights or interests of Illumina shall govern and control with respect

to the applicable subject matter.

2. COVENANTS AND WARRANTIES.

2.1            Registrations.

In the case any governmental registrations, licenses, permits or approvals (collectively, “Registrations”) are required

for the sale of the Products in the Territory, then Eurobio shall reasonably cooperate with CareDx in connection with obtaining the Registrations

and vice versa. At the request of Eurobio, CareDx shall register the Products or any component of any Product in the Territory in the

name of Eurobio. To the extent of any such request, if CareDx is prohibited by applicable law from registering Products in the name of

Eurobio and is required to identify itself to regulatory agencies as a distributor of Products, it may do so, identifying Product registered,

but it may not identify itself as the sponsor or manufacturer of the Product. Costs of registration shall be borne by CareDx, which shall

include registration renewal, and any other associated costs. In the event applicable law requires that Product registration be in the

name of CareDx, CareDx hereby agrees to transfer the Product Registration to any other person or company named by Eurobio or, cancel

the Product Registration when the transfer is not allowed by law, as may be requested by Eurobio at any time in its sole discretion.

CareDx shall maintain all appropriate administrative licenses and approvals to conduct its distribution activity in each country of the

Territory.

2.2            Compliance

with Laws. Each party shall comply with all governmental laws, regulations, and orders that may be applicable to its conduct under

this Agreement, including, without limitation, any laws, regulations, or orders that govern or affect the ordering, export, shipment,

import, sale (including government procurement), delivery, or redelivery of the Products in the Territory.

2.3            Product

Recalls. CareDx shall immediately inform Eurobio in writing in the event of any customer complaints with respect to the Products.

or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in

any way be affected or impaired thereby and the parties agree to replace such invalid, illegal or unenforceable term or provision with

similar thereto); or (xii) directly or indirectly, in any way dispute or impugn the validity of the Trademark, or LICENSOR's

sole ownership and right to use and control the use of the Trademark.

4.            Agreements

with Manufacturers. Subject to Section 13 (Sublicenses), LICENSEE may arrange with others to manufacture Licensed

Product or components thereof for the exclusive sale, use, and distribution by LICENSEE, its Affiliates and distributors that are

a permitted sublicensee in accordance with the terms of this Agreement.

5.            Quality.

(a)            Specifications,

Standards and Laws. LICENSEE acknowledges and is familiar with the high standards, quality, style, and image of LICENSOR, and LICENSEE

at all times shall conduct its business and use the Trademark and sell, distribute, market and exploit Licensed Products only in a manner

consistent with these standards, quality, style, and image. LICENSEE shall comply, in all material respects, with the specifications

and standards for the Licensed Products contained in the Specifications; provided that upon LICENSEE’s written notice to LICENSOR

that it wishes to modify or update the Licensed Products, the parties shall collaborate in good faith to update the applicable Specification

to reflect such changes in accordance with applicable laws and any other term of this Agreement, provided that any updated Licensed Products

shall be at least functionally equivalent to the prior version for LICENSEE’S intended use. In exercising its rights and performance

of its obligations under this Agreement, LICENSEE shall comply, and ensure that Manufacturers and sublicensees will comply, with all

applicable laws, regulations and ordinances, and industry standards, including S/H/E, and shall not act, ensure that Manufacturers and

sublicensees shall not act, in a manner that would reflect adversely upon the good name and reputation of LICENSOR or any of its programs,

products, properties or the Trademark. “Safety, Health, Environment (S/H/E)” means industry standards and other

standards promulgated or regulated by the US Occupational Safety and Health Administration, the US Environmental Protection Agency, state

or local agencies and, if applicable, other federal, state or local agencies charged with protecting safety, health, and environment,

and foreign equivalents, which in each case relate to employee safety, employee health and the natural or human environment.

(b)            Quality

Standards. LICENSEE acknowledges that the quality of Licensed Products must be the highest in order to preserve

and maintain LICENSOR's reputation and the goodwill inherent in the Trademark, and agrees that failure to adhere to LICENSOR's

quality standards as set forth on Exhibit C hereto (“Standards”) will impair the value and

goodwill associated with the Trademark. LICENSEE therefore agrees that prior to the first sale of any Licensed Product bearing

any new or modified Trademarks, or manufactured using any process or facility other than those used immediately prior to the Closing,

and thereafter from time to time following LICENSOR’s reasonable written request, but in no event, without good reason, in excess

of once every twelve (12) months, it shall, at its expense, submit three (3) representative production samples of the Licensed

Product, in accordance with Specifications, all documentation describing use and application of such Licensed Product, to LICENSOR for

written approval. LICENSOR shall provide written approval or disapproval of any Licensed Products within five (5) business

days after receipt thereof, with such approval not to be unreasonably withheld. LICENSOR’s failure to approve or disapprove within

such period shall be deemed approval. LICENSOR shall have the right, in its reasonable discretion, to approve or disapprove any Licensed Products. Once

LICENSOR's final review and approval have been obtained, LICENSEE agrees that it shall not deviate from the approved samples, Standards

and Specifications without LICENSOR’s written approval. If LICENSOR determines that the Licensed Product does

not conform to the approved samples, Standards and Specifications, LICENSEE shall immediately stop the manufacture, distribution

and sale of the nonconforming Licensed Product and conform Licensed Products per LICENSOR’s reasonable request.

and Right to Inspect.

(i)            LICENSEE

shall ensure that the production and/or manufacture of Licensed Products and/or Advertising Materials, whether by LICENSEE,

sublicensee or by third party manufacturers or suppliers selected by LICENSEE with LICENSOR’s approval (individually, a “Manufacturer”

and collectively, the “Manufacturers”), complies with the requirements of this Agreement, including those that are

set forth in this Section. LICENSEE shall ensure such compliance by Manufacturers before they contribute to production of Licensed

Products and at all times during such production. LICENSEE shall supply LICENSOR with the addresses of its manufacturing

facilities for the Licensed Products, as well as those of its sublicensees, if any, before any such facilities contribute to production

of Licensed Products. If LICENSEE becomes aware that any Manufacturer or sublicensee has used or is using Trademark for

any unauthorized purpose or in violation of this Agreement, LICENSEE shall immediately notify LICENSOR and, if so instructed by LICENSOR,

shall cause such Manufacturer or sublicensee, as applicable, to cease such use immediately.

(d)            Product

Safety.

(i)          Each

party shall promptly notify the other when and if either has reason to believe that any Licensed Product poses or may pose

a health or safety risk, or does not or may not comply with any laws or regulations. In addition, LICENSEE shall promptly notify LICENSOR

of any claims, lawsuits, reports or allegations related to the Licensed Products which could give rise to a reporting obligation

under federal and/or state laws. LICENSEE shall also give LICENSOR prompt notice of all product liability claims involving any Licensed

Product. LICENSEE (A) shall promptly provide LICENSOR with details of the events that gave or are giving rise to the consideration

of a possible recall, (B) shall keep LICENSOR promptly advised of decisions concerning the recall, and (C) shall show LICENSOR

any draft announcements concerning the affected Licensed Product before making such announcement, and give LICENSOR the opportunity

to collaborate with LICENSEE on them. LICENSEE shall reimburse LICENSOR for its costs for any recall.

6.            Advertising

Materials.

(a)            Approval

of Advertising Materials. LICENSEE shall not use any Advertising Materials for which LICENSOR has not approved the Trademark

Format. Advertising Material currently marked with any Trademarks, as used immediately prior to the Closing, are hereby deemed approved

by LICENSOR. With respect to new Advertising Materials from and after the Closing, LICENSEE shall electronically submit one (1) draft

copy or otherwise send three (3) draft copies of any new Trademark Format for any such Advertising Materials to LICENSOR

for its review and written approval before printing, producing or using such Advertising Materials. For clarity, the advertising

copy for Advertising Materials of LICENSEE shall not be subject to review and approval of LICENSOR hereunder, only usage of Trademarks

in connection therewith, and only to the extent that such usage is new (e.g., differs from the Trademark Format).

(b)            Time

for Approval. LICENSOR shall use reasonable efforts to provide written approval or disapproval of any Advertising Materials within

five (5) business days after receipt thereof. LICENSOR’s failure to approve or disapprove within such period shall be deemed

disapproval, unless LICENSOR subsequently notifies LICENSEE of its written approval. LICENSOR shall not unreasonably withhold approval

of any Advertising Materials.

Endorsement. LICENSEE shall not use a personality or celebrity to endorse or promote any Licensed Products or any product or service

that bears or makes any use of or reference to the Trademark, or to use Advertising Materials, without LICENSOR’s prior written

approval.

7.            Protection

of the Trademark.

(a)            Registrations. Upon

LICENSEE’S request, and at LICENSEE’S expense, LICENSOR will register the Trademark in additional jurisdictions during the

Term. LICENSOR shall have the right, in its sole discretion, to file trademark, trade dress, copyright, logos, graphical designs, or

other applications in the Territory or elsewhere, relating to the use or proposed use by LICENSEE of the Trademark and

to record this Agreement. Such filings shall be made in the name of LICENSOR or in the name of any third party selected by LICENSOR.

LICENSEE shall assist LICENSOR at LICENSOR’s expense, to the extent necessary in LICENSOR’s opinion, in procuring, protecting

and defending any of LICENSOR’s rights in the Trademark, in the filing and prosecution of any trademark application, copyright

application or other applications for the Trademark, the recording or canceling of this Agreement, and the publication of

any notices or the doing of any other act or acts with respect to the Trademark, including the prevention of the use thereof by

an unauthorized person, firm or corporation, that in the judgment of LICENSOR may be necessary or desirable. For these purposes, LICENSEE

shall supply LICENSOR, free of cost to LICENSOR, such samples, containers, labels and similar materials as may reasonably be required

in connection with any such actions. LICENSOR shall, at LICENSEE’s expense, maintain all registrations set forth on Exhibit A

during the Term.

(b)            Assignment

by LICENSEE. LICENSEE acknowledges that (a) LICENSOR is the owner of the Licensed Mark throughout the world and all goodwill

related thereto, and (b) all use of the Trademark by LICENSEE or sublicensees under this Agreement and any goodwill accruing from

such use will inure solely to LICENSOR’s benefit. To the extent LICENSEE acquires any rights to any of the Trademark, LICENSEE

hereby assigns and transfers to LICENSOR all such rights, together with the goodwill of the business in connection therewith, and agrees

to execute any documentation relating to such assignment. LICENSEE hereby further assigns and transfers to LICENSOR its entire worldwide

right, title, and interest in and to all trademarks created using all or any portion of the Trademark or that are confusingly

similar to the Trademark; except to the extent of any co-branding, in which case LICENSEE shall retain ownership of its proprietary marks

included in such co-branding.

Notice. LICENSEE shall affix or cause its authorized manufacturing sources to affix to the packaging for the Licensed

Products and Advertising Materials the following notice (and such other notices as may be reasonably requested from

time to time by LICENSOR), as applicable; (i) “[Trademark®] is a registered trademark of CareDx, Inc. used under

license”; or (ii) “[Trademark] is a trademark of CareDx, Inc. used under license.”

(d)            Notwithstanding

anything to the contrary herein, promptly after Closing, LICENSOR and LICENSEE shall establish standard approved formats for the Trademarks

(e.g., logo design), and Licensee may use the Trademarks in such approved formats, which, by default, shall be their current formats

as of Closing (each a (“Trademark Format”) without the need for further approval from LICENSOR.

8.            Enforcement. If

LICENSEE learns that a third party may be infringing the Trademark, LICENSEE shall promptly provide LICENSOR with written

notice providing any details it knows about the use. LICENSEE shall not take any action without LICENSOR’s written consent. LICENSOR

shall decide what, if any, action to take, but shall have no obligation to take any action. LICENSEE shall, at LICENSOR’S

expense, cooperate with LICENSOR in any action it takes to stop infringement of Trademark. LICENSOR may settle any dispute relating to

the use of the Trademark without notice or compensation to LICENSEE; provided that any such settlement shall not impair the

rights of LICENSEE hereunder without LICENSEE consent, not to be unreasonably withheld, and LICENSOR shall retain the proceeds of any

settlement or proceeding.

9.            Indemnification.

(a)            Indemnification

by LICENSEE. LICENSEE agrees to indemnify, defend and hold LICENSOR and its Affiliates and the officers, directors, shareholders,

employees and agents of any of the foregoing harmless against any liability, losses, damages, penalties, claims, actions, suits, judgments

or settlements of any nature or kind (including reasonable costs of investigation, reasonable attorneys’, accountants’ and

expert witnesses’ fees, and reasonable costs and expenses), incurred by any such person by reason of LICENSEE’s use of the

Trademarks.

(b)            Claims

Procedures. With respect to the foregoing indemnification obligations: (i) LICENSEE agrees promptly to notify and keep

LICENSOR fully advised with respect to any Claims; (ii) LICENSOR shall have the right to assume, at its sole expense, the defense

of a claim or suit made or filed against the LICENSEE; (iii)  LICENSOR may participate in the defense of such Indemnified Claim,

with counsel of its own choosing and at its own cost and expense; and, (iv) LICENSEE shall not compromise or settle any Claim without

LICENSOR’s prior written consent.

10.            Intentionally

omitted.

11.            Term

and Termination.

(a)            Term.

This Agreement will commence as of the Effective Date and shall continue for five (5) years thereafter, unless terminated earlier

in accordance with the terms of this Agreement, or by mutual written agreement of the Parties hereto (the “Term”).

Notwithstanding the foregoing, if LICENSEE desires to extend the term for additional renewal periods of two (2) years, then LICENSEE

shall provide written notice to LICENSOR prior to expiration of the Term, and the parties shall discuss in good faith such extension.

Unless LICENSOR has a good faith and reasonable reason or justification for not approving such extension, the Term shall be extended

by such two (2) year periods.

(b)            Breach. If LICENSEE

or any sublicensee or Manufacturer is documented to have materially breached this Agreement, and LICENSEE fails to

cure the breach within thirty (30) days after LICENSEE receiving written notice thereof, this Agreement shall terminate at

the end of the thirty (30) day period; provided, however, that this Agreement shall not be terminated if, during such period, the LICENSEE

is diligently and in good faith taking reasonable steps to cure such breach.

of Termination. Upon expiration or termination of this Agreement, LICENSEE and all sublicensees shall immediately

discontinue manufacturing, selling, advertising, distributing, and using the products or services bearing or making a reference

to Trademark and any and all Advertising Materials, and terminate all agreements with manufacturers, distributors,

and others which relate to the manufacture, sale, distribution, and use of the foregoing. The provisions of Sections 3,

5(d), 9, 10, 11(e), 12, 13(e) and 14 herein shall survive any termination

or expiration of this Agreement. Notwithstanding the foregoing, absent a termination for material breach, LICENSEE shall have the

right to market and sell all remaining inventory branded in accordance with the terms and conditions hereof for a period not to exceed

twelve (12) months after expiration.

business operations and strategies, goods and services, customers, pricing, marketing, and other sensitive and proprietary information

Disclosing Party’s Confidential Information with at least the same degree of care as the Receiving Party would protect its own

Confidential Information, but in no event with less than a commercially reasonable degree of care; (ii) not use the Disclosing

Party’s Confidential Information, or permit it to be accessed or used, for any purpose other than to exercise its rights or perform

its obligations under this Agreement; and (iii) not disclose any such Confidential Information to any Person, except to the Receiving

the foregoing, LICENSEE shall be under no obligation to renegotiate existing distribution or manufacturing agreements of the Quark Entities.

AGREEMENT (this “Agreement”) is entered into and made effective as [_______], 2026 (the “Effective

Date”), by and among CareDx, Inc., a Delaware corporation (“Provider”) and [●], a

[●] corporation ( “Recipient”).1, Capitalized terms used but not defined herein will have

the meanings ascribed to them in the Purchase Agreement (as defined below).

RECITALS

A.            The

parties hereto have entered into that certain Purchase Agreement, dated as of April 15, 2026 (the “Purchase Agreement”),

whereby Provider has agreed to sell to [Eurobio Scientific S.A./Recipient] certain assets of Provider related to the Quark Business and

the issued and outstanding shares of CareDx AB, a Swedish company and wholly-owned subsidiary of Provider.

B.            In

connection with the Purchase Agreement, Provider wishes to provide certain Transition Services (as defined below) to Recipient and Recipient

wishes to receive such Transition Services pursuant to the terms and conditions set forth in this Agreement.

NOW, THEREFORE, in consideration

of the foregoing and the mutual covenants, conditions and provisions contained herein and in the Purchase Agreement, and for other good

and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.            TRANSITION

SERVICES.

(a)            Scope

of Services. Subject to the terms and conditions of this Agreement, Provider will use reasonable best efforts to provide, or cause

its Affiliates to use reasonable best efforts consistent with good industry practice and with at least the same level of quality, timeliness

and care as provided to the Quark Business during the twelve (12) month period prior to the Effective Date to provide, to Recipient the

transition services described in Exhibit A (each, a “Transition Service” and collectively, the

“Transition Services”) during the applicable service period set forth on Exhibit A (each, a “Transition

Period”), in accordance with and subject to any applicable limitations or conditions set forth on Exhibit A.

The parties hereto acknowledge the transitional nature of the Transition Services and Recipient agrees to use reasonable best efforts

to transition, as promptly as practicable following the Closing, each Transition Service to its own internal organization or to obtain

services from alternative third-party sources in lieu of the Transition Services provided by Provider. This Agreement imposes no obligation

on Provider to perform any services other than the Transition Services expressly described in this Agreement or in Exhibit A

attached hereto, as it may be amended or supplemented as mutually agreed by the parties hereto from time to time in accordance with terms

of this Agreement. Provider will use reasonable best efforts to perform the Transition Services in a manner generally consistent with,

and with the same standard of care, in all material respects and without degradation in service levels, as such services were provided

to the Quark Business during the twelve (12) month period prior to the Effective Date, subject to Recipient fulfilling its obligations

under this Agreement and providing sufficient information, resources, and access as reasonably necessary for Provider to satisfy its

obligations under this Agreement. Under no circumstances will Provider be expected to modify its existing systems or processes, vendor

arrangements or business terms and conditions from those in existence prior to the Effective Date except to the extent reasonably necessary

to facilitate the transition and separation of the Quark Business as contemplated by this Agreement. Notwithstanding anything in this

Agreement to the contrary, Provider will have no obligation to perform any custom development work or implement any new product or service

features or functionalities in connection with the provision of the Transition Services other than reasonable configuration, data extraction,

migration assistance and knowledge transfer necessary to the transition and separation of the Quark Business as contemplated by this

Agreement.

Note to Draft: Eurobio entity as service recipient TBD.

(b)            Restricted

Contract Assets; Shared Contracts.

(i)            In

the event that Provider is unable to assign to Recipient (or its affiliate, as applicable) a supply or vendor agreement that is exclusively

related to the Quark Business as contemplated pursuant to Section 2.5 of the Purchase Agreement, then for a period of up to twenty-four

(24) months after the Closing Date (a “Quark Supply Agreement”), Provider and Recipient shall work together

in good faith and use best efforts to ensure that Recipient continues to receive the products or services supplied under such Quark Supply

Agreement by implementing one or more of the following arrangements: (a) Provider shall assist Recipient in obtaining its own replacement

supply agreement with the applicable supplier or vendor on commercially reasonable terms, or, to the extent deemed necessary by Recipient,

an alternative supplier or vendor that can provide substitute products or services for those provided under the Quark Supply Agreement,

as agreed by the parties acting reasonably and in good faith (which assistance from Provider shall include providing the introduction

to the relevant supplier or vendor and using commercially reasonable efforts to facilitate the consummation of the replacement supply

agreement between Recipient and such supplier or vendor), (b) to the extent Provider is not restricted under the applicable Quark

Supply Agreement, Provider shall continue to order and purchase the products under the Quark Supply Agreement, at Recipient’s direction,

and Provider shall resell such products to Recipient, provided that Recipient shall reimburse Provider only for its acquisition costs

therefor with no mark-up, or (c) in the case neither of the approaches set forth in (a) or (b) are feasible, then Provider

will continue to order and purchase products under such Quark Supply Agreement, at Recipient’s direction, and Provider shall enter

into a manufacturing agreement with Recipient (or one of its Affiliates) in the form attached hereto as Exhibit B, and a

distribution agreement with Recipient (or one of its Affiliates) in the form attached hereto as Exhibit C, providing for

the supply of the products purchased by Provider under the Quark Supply Agreement to the Recipient (or one of its Affiliates), at the

cost paid by Provider for such products without markup, in order for Recipient or such Affiliate to manufacture the products of the Quark

Companies with such supplied products in the same manner as such products are manufactured by the Quark Companies on the Effective Date

and to appoint Recipient (or one of its Affiliates) as Provider’s exclusive distributor for such finished products, with Recipient

(or such Affiliate) being entitled to keep all proceeds from the sale of any such finished products under the Distribution Agreement

without payment of any royalties or other amounts to Provider.

(ii)            In

the case of any Shared Contract under which any rights or benefits are relied upon by the Quark Companies or are required for the conduct

of the Quark Business, as determined by Recipient in its discretion, the Parties will cooperate with each other in good faith and use

commercially reasonable efforts to facilitate the negotiation and entry by Recipient (or one of Quark Companies) into a new agreement

with the same counterparty on equivalent economic and other terms with the same or a reasonably acceptable replacement vendor (as mutually

considered by Provider and Recipient, and determined by Recipient in its reasonable discretion) for the provision by such vendor of the

same or materially similar products or services to Recipient or the applicable Quark Company following the Closing as are provided to

such Quark Company as of the Effective Date and otherwise upon the applicable vendor’s standard terms and conditions (or such other

terms and conditions as may be negotiated by Recipient with such vendor with the reasonable co-operation and assistance of Provider)

(each such new Contract, a “Replacement Contract”), with such Replacement Contract to become effective as soon

as practicable following the Closing. Pending the entry by the Recipient or the applicable Quark Company into such Replacement Contract,

subject to the terms and conditions of this Agreement, Provider will use commercially reasonable efforts to make available the assets,

products or services under the applicable Shared Contract to Recipient to the same extent as such assets, products or services were provided

to the relevant Quark Company prior to the Closing, as a Transition Service hereunder and the parties hereto will update Exhibit A

to include such Transition Service, unless the parties mutually agree on an alternative arrangement that would give Recipient the benefit

of the same or a substantially similar service. In the case of a Shared Contract under which the relevant Quark Company is required to

pay for such assets, products or services directly to the applicable vendor, whether pursuant to the terms of such Shared Contract, or

any insertion order, statement of work, order form or similar document entered into by such Quark Company under such Shared Contract

(each, a “Recipient SOW”), Recipient hereby agrees to timely discharge such payments to the relevant vendor

in full in accordance with the terms of such Shared Contract. In the case of any Shared Contract under which Provider pays the relevant

vendor for the assets, products or services under such Shared Contract that are used or relied on by any Quark Company, Recipient will

pay the Fees as set forth in Exhibit A of this Agreement for such Transition Service. The Transition Period for the Transition

Services hereunder provided in connection with Shared Contracts will not extend beyond the earlier of (A) such time as the Replacement

Contract has been obtained or (C) the date that is twenty-four (24) months following the Closing Date, unless otherwise agreed

by Provider, such agreement not to be unreasonably withheld, conditioned or delayed.

(iii)         Provider

will not be required to renew or replace any Shared Contract (in its entirety or with respect to the portion of the assets, products

or services provided thereunder that are used by the Quark Companies) for which Transition Services are provided hereunder that expires

or is due for renewal during the term of this Agreement; provided that Provider shall use commercially reasonable efforts to support

Recipient in obtaining replacement arrangements and shall not allow any Shared Contract to terminate due to Provider’s breach or

voluntary action. During the Transition Period, Provider will not materially modify the pricing or other material terms of, or terminate

(other than as set forth in the preceding sentence), any portion of a Shared Contract, or any Recipient SOW, that relate to assets, products

or services provided to Recipient hereunder as a Transition Service without Recipient’s prior written approval (such approval not

to be unreasonably withheld, delayed or conditioned) except for any such modification that applies in the same manner to Provider’s

use of such assets, products or services in its other businesses

(iv)         Recipient

will not renew any Recipient SOW or enter into any new Recipient SOW during the Transition Period applicable to the relevant Shared Contract

without Provider’s prior written approval.

Personnel.

(i)            Provider

may satisfy its obligation to provide the Transition Services hereunder by (A) causing one or more of its Affiliates to provide

such Transition Services or (B) at reasonable expense, subcontracting any of the Transition Services or any portion thereof to,

or procuring any of the Transition Services or portion thereof from, any other Person; provided that, in each case of clauses

(A) and (B), Provider remains liable for the performance of such subcontractors and their compliance with the terms of this Agreement;

and, provided, that, any such subcontractors are approved by Recipient as having appropriate skill, experience and training consistent

with past practice.

(ii)          Provider

will have the right, in its discretion, to (A) designate which personnel it will assign to perform each Transition Service; provided,

that, Provider shall assign personnel with appropriate skill, experience and training consistent with past practice, and (B) remove

and replace such personnel at any time. In performing their respective duties hereunder, all such employees, contractors and other representatives

of Provider and its Affiliates (excluding, for the avoidance of doubt, the Quark Companies and their personnel) will be under the direction,

control and supervision of Provider and its Affiliates (excluding the Quark Companies and their personnel), and Provider and such Affiliates

will have the sole right to exercise all authority with respect to the employment (including termination of employment), engagement,

assignment and compensation of such employees, contractors and representatives. Provider shall use commercially reasonable efforts to

provide reasonable prior notice of any material changes to key personnel involved in the provision of Transition Services.

(d)            Interpretation.

Recipient acknowledges that Provider is not in the business of providing services like the Transition Services on a commercial arm’s-length

basis to independent third parties, and that this Agreement is only required for specific circumstances related to the consummation of

the Transactions on a transitional basis only. The provisions of this Agreement will be interpreted in that context.

2.            COOPERATION.

(a)            Cooperation.

The parties hereto will use reasonable best efforts to cooperate with each other in all matters relating to the provision and receipt

of the Transition Services. Subject to the terms and conditions of this Agreement, and subject to Recipient’s compliance with Provider’s

information security, access, nondisclosure and confidentiality and other reasonable policies and requirements, such cooperation will

include exchanging information, providing necessary access to people, equipment and systems, and cooperating with respect to obtaining

and providing all consents, licenses, sublicenses, approvals, and/or rights reasonably necessary to permit each party to perform its

obligations hereunder.

(b)            Administration.

Each of the parties hereto will appoint a representative to serve as the main point of contact for such party for the purposes of this

Agreement for each individual Transition Service as set forth on Exhibit A (such person, the “Transition Representative”).

At its discretion, each party hereto may replace or appoint a successor Transition Representative with written notice to the other party.

The relevant Transition Representatives for the Transition Services hereunder will meet to discuss the performance of the Transition

Services on weekly basis within the first ninety (90) days if the Closing and then on a monthly basis to ensure the orderly provision

of the Transition Services, and in any event at least monthly, and will have the authority to address and remedy problems related to

the provision of the Transition Services to the extent consistent with this Agreement.

The parties hereto will work together in good faith to resolve all disputes under this Agreement. Disputes will be first escalated to

the managers of each party with the most direct responsibility for the dispute and the Transition Representative. Any disputes unresolved

after 10 business days will then be escalated to the respective managers’ next level of management. If such second level of managers

cannot resolve the dispute within the next 10 business days thereafter, then the dispute will be escalated to (i) the chief executive

officer, chief financial officer or chief operational officer of Recipient and (ii) a senior-level executive of Provider. If such

persons cannot resolve the dispute within the next 10 business days, then any party may pursue any available legal remedy and resolution

of such dispute pursuant to Section 9(l).

(d)            Access

and Confidentiality. While accessing any data processing or communications services or facilities of the other party, each party

will, and will cause its Representatives and subcontractors to, comply in all material respects with the other party’s corporate

information and physical security policies (including policies with respect to protection of proprietary information and other policies

regarding the use of computing resources) as in effect and notified to such party from time to time. Recipient will not attempt to gain

access to or use any information or systems of Provider and its Affiliates except as expressly authorized by Provider. The parties hereto

acknowledge that use and disclosure of each party’s confidential information will be governed by the terms of the Purchase Agreement

and the Mutual Non-Disclosure Agreement dated effective as of November 20, 2024 between Provider and Eurobio Scientific SA/Recipient

(the “Confidentiality Agreement”).

(e)            Identification

of Dependencies. Within two (2) weeks after the execution of the Purchase Agreement, Provider shall deliver to Recipient a

first draft of a dependency map that lists out all known interdependencies relating to the Transition Services. During the period following

delivery of such draft dependency map and continuing through the Closing, Provider and Recipient shall use reasonable best efforts to

update such dependency map, including adding additional detail as needed.

(f)            Cybersecurity

and Data Protection. Following execution of the Purchase Agreement and continuing through the term of this Agreement, Provider shall

use reasonable best efforts to maintain its data security and cyber security systems and processes with at least the same level of quality,

timeliness and care as Provider maintained during the twelve (12) month period prior to the Effective Date.

3.            FEES

AND PAYMENT.

(a)            Fees.

As consideration for providing the Transition Services, Recipient will pay, and Buyer will cause Recipient to pay, to Provider the amount

set forth on Exhibit A for each Transition Service (“Fees”) in accordance with the invoicing procedures

set out in Section 3(d). The parties hereto acknowledge and agree that the Fees for Transition Services that pertain to

Transition Services performed by personnel of Provider will be calculated and charged on the basis of Provider’s Fully Burdened

Cost for the relevant Provider personnel (as determined in a manner consistent with the historical methods of Provider’s allocation

of costs to the Quark Business), in accordance with the invoicing procedures set out in Section 3(c). “Fully Burdened

Cost” means the fully-burdened costs of the personnel of Provider (or any of its Affiliates) providing Transition Services

hereunder which, in the case of contractors, shall mean the direct compensation paid to contractors and, in the case of employees, shall

mean the Employee Costs, which, in each case, (i) are paid or payable to such personnel solely in respect of their provision of

the Transition Services and (ii) will be charged at Provider’s actual cost, provided, that, such costs shall be consistent

with Provider’s historical allocation methodologies and shall not include any duplicative overhead or costs not reasonably attributable

to the provision of the Transition Services), plus an overhead charge in an amount to be agreed as set forth in Exhibit A (such

overhead charge, the “Markup”). “Employee Costs” shall mean, with respect to any

employee of Provider (or any of its Affiliates) providing Transition Services hereunder, the sum of (i) his or her salary, wages

(including wages in respect of paid vacation or paid time off), bonuses, cash incentive compensation, commissions and equity incentive

compensation, (ii) Provider’s (or its Affiliate’s) share of the premiums (or equivalents) for workers compensation,

unemployment, fringe and welfare benefits under Provider’s (or its Affiliate’s) employee benefit plans (for clarity, reduced

by the contributions for coverage paid by the applicable employee), (iii) Provider’s (or its Affiliate’s) employer

non-elective and matching contributions to Provider’s tax-qualified defined contribution retirement plan, and (iv) Provider’s

(or its Affiliate’s) share of payroll and other employment taxes. Based on projected scope and lengths outlined on Exhibit A, the

aggregate Fees will be capped at USD $1 million dollars (the “Cap”), provided that if, at any time, it becomes

reasonably apparent that the aggregate Fees will surpass the Cap, then the parties will, at the election of either one of them, negotiate

in good faith an alternate Cap, provided, however, that the Fees as determined above shall continue to accrue until such alternate Cap

is agreed to.

(b)            Upon

Recipient’s request, Recipient and Provider will collaborate together in good faith to establish budgeting and cost forecasting

procedures to avoid cost overages or otherwise to facilitate delivery of the Transition Services.

or indirect costs or expenses, incurred by Provider in connection with providing a Transition Service, including license fees or other

payments to third-party vendors and service providers, costs and expenses of maintaining redundant instances, paying additional or higher

pricing or rates under new or replacement Contracts for the Quark Business or with respect to Restricted Split Interests, purchasing

additional data storage or incurring technical standup costs and other costs to facilitate the separation of the Recipient and the Business

from the other businesses of Provider and its Affiliates, in each case, to the extent reasonably necessary and actually incurred in connection

with the provision of the Transition Services and supported by reasonable documentation (collectively, “Out-of-Pocket Costs”),

which Out-of-Pocket Costs will be reimbursed by Recipient in accordance with the invoicing procedures in Section 3(d). The

parties will coordinate to generally to ensure that expenses under this Agreement are in line with historical expenses and Provider will

notify Recipient in advance of any exceptional expenses that may be incurred to enable Recipient to approve any such expenses in advance.

Upon Recipient’s request, Recipient and Provider will collaborate together in good faith to establish spending thresholds for Out

of Pocket expenses above which prior approval is required.

(d)            Transition

Service Adjustment. If an adjustment in the time or work performed as part of the Transition Services is required after Provider

commences the Transition Services, the applicable scope of work, time and compensation will be agreed in writing by Provider and Recipient

prior to the commencement of additional work or any extension of the Transition Period, as applicable.

(e)            Payment.

All Fees and Out-of-Pocket Costs will be payable to Provider on a monthly basis within 30 days following Recipient’s receipt of

Provider’s monthly invoice for Fees and Out-of-Pocket Costs incurred during the applicable calendar month. All payments hereunder

will be paid in U.S. Dollars and made by wire transfer of immediately available funds to a bank account specified by Provider in writing.

All Fees and Out-of-Pocket Costs owed under this Agreement and not paid when due will accrue late charges at the rate of 1.5% per month,

or the highest rate permitted by applicable Law, whichever is lower. If Recipient discovers an error or omission in any invoice, Recipient

will provide prompt written notice to Provider and Provider’s Transition Representative of such error or omission for resolution

in accordance with Section 2(c). Recipient shall have the right, upon reasonable prior notice, to audit Provider’s

records relating to Fees and Out-of-Pocket Costs no more than once annually.

(f)            Extension

such Transition Services.

(g)            Taxes.

Except as otherwise noted on the relevant invoice, the Fees do not include any Taxes. Recipient will be responsible for and pay any and

all federal, state or local sales, use, value-added, goods and services and similar Taxes, duties, charges or levies (and any related

interest and penalties) imposed on, or in connection with the provision of the Transition Services hereunder, but excluding any Taxes

measured by or imposed on the Provider’s net income. All payments made by or on behalf of Recipient under this Agreement will be

made without deduction or withholding for any Taxes, unless Recipient is required to deduct or withhold such Taxes under applicable Law.

If Recipient is required by any applicable Law or regulation to withhold any amount for Taxes from any payment due to Provider under

this Agreement, then Recipient will (i) make such withholdings as are required by applicable Law, (ii) timely pay the full

amount deducted or withheld to the appropriate Governmental Authority and (iii) pay such additional amounts to the Provider as

may be necessary so that the net amount received by Provider after such withholding will not be less than the amount Provider would have

received if such deductions or withholding had not been made. At Provider’s request, Recipient will provide Provider with reasonably

satisfactory documentation evidencing the payment to the appropriate Governmental Authority of any amounts so withheld or deducted.

(h)            No

Set-Off. Each party hereto hereby acknowledges and agrees that it has no right under this Agreement to set off, discount or otherwise

reduce or refuse to pay any amounts owed to the other party under this Agreement against any other amount owed to it by the other party,

whether under this Agreement, the Purchase Agreement, other Transaction Documents or otherwise; provided that Recipient may set off amounts

finally determined to be owed by Provider pursuant to this Agreement.

4.            TERM

AND TERMINATION; SUSPENSION.

(a)            Term.

Unless earlier terminated, this Agreement is effective beginning on the Effective Date and will remain in effect until termination or

expiration of the last to expire Transition Period.

(b)            Termination

for Convenience. Recipient will use commercially reasonable efforts to transition the Quark Companies and their Affiliates from reliance

upon, and terminate, the Transition Services that Recipient is receiving hereunder as soon as reasonably practicable following the Effective

Date. Unless otherwise set forth on Exhibit A, Recipient may terminate any or all Transition Service(s), or any portion

thereof, upon 30 days’ written notice to Provider, without further liability or cost to Recipient; provided that, notwithstanding

the foregoing, Recipient will remain liable for non-cancellable costs that were incurred in good faith, are documented, and were not

reasonably avoidable following such notice incurred or committed to be incurred by Provider in respect of any such Transition Services

for the then current Transition Period; provided that in the event of early termination, any fixed or monthly fees agreed for Transition

Services shall be prorated to correspond to the actual Transition Period. Notwithstanding anything in the foregoing to the contrary,

Recipient acknowledges that certain Transition Services are dependent upon the provision of other Transition Services and the termination

of one Transition Service (in whole or in part) may not be possible without the termination or reduction of a number of other Transition

Services (in whole or in part) and, that in the event any such a termination or reduction, Provider will notify Recipient thereof in

advance in writing, permitting Recipient a reasonable period and in any event not less than ten (10) Business Days, to adjust its

approach continue Transition Services otherwise planned for termination. In the event Recipient has been so notified and continues in

its plan for termination of the related Transition Service, Provider may, upon written notice to Recipient, terminate or reduce any other

Transition Service that it has notified Recipient is dependent upon the Transition Service that has been terminated by Recipient.

for Cause. Either Provider or Recipient may terminate this Agreement in the event that the other party materially breaches this Agreement

and such material breach remains uncured for 30 days following receipt of written notice of such breach by the non-breaching party. Provider

may further terminate a Transition Service hereunder with notice to Recipient in the event that Provider receives notice from a counterparty

to any Shared Contract in connection with which such Transition Service is provided that the provision of Transition Services under such

Contract by Provider constitutes a breach of such Shared Contract or if any actions or omissions of Recipient in connection with such

Transition Service have caused or are reasonably expected to cause a breach of such Shared Contract; provided, that, Provider shall provide

prompt written notice of any such counterparty notice and shall take commercially reasonable steps to mitigate any impact of such termination

as contemplated through alternative supply arrangement or otherwise in Section 1(b) above.

(d)            Partial

Termination. In the event of any termination or expiration with respect to one or more of the Transition Services, but not all of

the Transition Services, this Agreement will continue in full force and effect with respect to any Transition Service(s) not terminated

or expired in accordance with this Agreement. Upon termination of this Agreement, or upon the termination or expiration of all of the

Transition Services in accordance with this Section 4, Provider will cease to perform the Transition Services, and Recipient

will pay to Provider all sums due to Provider pursuant to this Agreement for the Transition Services performed through the effective

date of termination, if any. Termination of this Agreement or termination or expiration of any Transition Service in accordance with

this Section 4 will not relieve any party from its obligations or liabilities arising hereunder prior to the date of such

termination or expiration, nor will it affect the rights of any party with respect to any claims or damages it may have suffered as a

result of any breach of this Agreement by the other party.

(e)            Effect

of Termination. Sections 3, 4(d), 4(e), 6(a), 7, 8 and 9 will survive any expiration

or termination of this Agreement.

5.            COMPLIANCE.

(a)            Restrictions

on Services. Each party hereto will comply in all material respects with all applicable Laws that govern the conduct of its own business

operations with respect to the performance of its obligations under this Agreement and receipt and use of Transition Services, as applicable.

Notwithstanding anything in this Agreement to the contrary, Provider will not be obligated to provide a Transition Service that, in Provider’s

reasonable discretion, (i) would be unlawful for Provider to provide under any applicable Law or (ii) would breach the terms

of any existing agreement between Provider and any third party or that would otherwise require the consent or similar approval of a third

party; provided that Provider shall use commercially reasonable efforts to mitigate or overcome such limitation and minimize disruption

to Recipient. If Provider is unable to provide a Transition Service due to the limitations described in this Section 5(a),

the parties will work together and use commercially reasonable efforts to arrange a substitute means of obtaining such service or obtaining

replacement or substitute agreements that would permit Provider to provide each such Transition Service, in each case at Recipient’s

sole cost and expense. In the event, and during the period, that Provider or its Affiliates is wholly or partially prevented from, or

delayed in, providing one or more of the Transition Services by applicable Law or by order of a Governmental Authority (a “Legal

Prohibition”), or because providing such services would breach the terms of any existing agreement between Provider and

any third party or would otherwise require the consent or similar approval of a third party (“Contractual Restriction”),

(A) neither Provider nor its Affiliates will be obligated to deliver the affected Transition Services during such period, (B) Provider

will promptly provide Recipient with notice of any Transition Services that will be suspended pursuant to clause (A), stating the

date and extent of such suspension and the cause thereof and (C) the parties hereto will use their commercially reasonable efforts

to resolve the Legal Prohibition or Contractual Restriction. The parties hereto will cooperate and use commercially reasonable efforts

to minimize the impact of any Legal Prohibition or Contractual Restriction on the provision of Transition Services hereunder; provided

that such efforts need not include expenditure of funds, the payment of consideration or the grant of rights or other accommodations

to third parties. Provider shall promptly notify Recipient in writing of any anticipated interruption and shall cooperate in implementing

reasonable alternative arrangements.

(b)            Contractual

Obligations. Recipient will comply with and perform all terms and conditions of the Quark Supply Contracts and the Shared Contracts

as they relate to Recipient’s receipt and use of Transition Services, including, without limitation, complying with the terms and

conditions of such Contract and discharging or reimbursing Provider for all payment obligations set forth in any such Contract, or any

statement of work, order form or similar document thereunder, as they relate to the receipt by Recipient or its Affiliates of the benefits

of such Transition Services under such Contracts, as may be further described in Exhibit A.

Regulatory Advice. Notwithstanding anything in this Agreement to the contrary or the accompanying exhibits and schedules, Provider

is not responsible for ensuring Recipient’s regulatory and legal compliance under applicable Law and the parties hereto agree that

the Transition Services are not a substitute for Recipient’s performance of any such compliance obligation or the engagement of

appropriate advisors to assist with any such compliance obligation. All regulatory and legal compliance matters relating to Recipient’s

use of the Transition Services will be exclusively the responsibility of Recipient. All liability and third party claims arising from

regulatory and legal compliance matters relating to the business of Recipient will be exclusively the liability of Recipient.

6.            INTELLECTUAL

PROPERTY.

(a)            No

Transfer. Subject to Section 6(b), this Agreement and the performance of the Transition Services hereunder will not

affect, or result in the transfer of, any rights in or to or the ownership of any Intellectual Property or other rights of either party.

No party hereto will gain any rights of ownership of any Intellectual Property or other property owned by any other party by virtue of

this Agreement or the provision of the Transition Services hereunder, by implication, estoppel or otherwise.

CareDx Announces Agreement to Divest Lab Products Business to EuroBio

Scientific for $170 Million and Announces First Quarter Preliminary Financial Results

Transaction Expected to Sharpen CareDx’s Focus on Core Precision

Medicine Testing Services and Patient and Digital Solutions, Improve Financial Flexibility, Simplify Operating Model, and Support AEBITDA

Margin Expansion

Expects First Quarter Testing Services Revenue Growth of Approximately

48% Year Over Year, Testing Volume Growth of Approximately 17% Year-Over-Year

BRISBANE,

Calif. — (BUSINESS WIRE) — CareDx, Inc. (Nasdaq: CDNA) — The Transplant Company™, a leading precision medicine

company focused on the discovery, development, and commercialization of clinically differentiated, high-value healthcare solutions

for transplant patients and caregivers, today announced that it has entered into a definitive agreement to divest its Lab Products business

to EuroBio Scientific for cash consideration of $170 million. The transaction has been approved by the boards of directors of both companies.

CareDx also announced today preliminary financial results for the first quarter of 2026.

CareDx’s Lab Products business consists of IVD (in vitro diagnostic)

PCR kits for rapid deceased donor HLA (human leukocyte antigen) typing, IVD NGS-based (next-generation sequencing) kits for transplant

recipient HLA typing globally, and IVD NGS-based monitoring assays for solid organ and stem cell transplant recipients outside of North

America. As a global IVD kit business with distinct manufacturing, regulatory, and commercial requirements, Lab Products operates under

a different model than CareDx’s core U.S.-based Precision Medicine Testing Services and its Patient and Digital Solutions. The divestiture

is intended to simplify CareDx’s operating model and support disciplined capital redeployment toward opportunities aligned with

its Precision Medicine Testing Services model.

“This divestiture allows us to strategically focus on our core Testing Services and Patient

and Digital Solutions, where our solutions-selling strategy is working. In the first quarter, these segments delivered 48% and 33% year-over-year

revenue growth, respectively,” said John Hanna, President and CEO of CareDx. “Having partnered with EuroBio Scientific since

2014, we believe their global scale and broad IVD capabilities positions them well to execute the Lab Products business and continue providing

the highest quality service to our IVD customers and patients worldwide.”

Highlighted Terms of the Agreement

· CareDx to divest its Lab Products business to EuroBio Scientific

· Total consideration of $170 million in cash at closing

· CareDx

to provide transition services to EuroBio Scientific for at least 6-months at EuroBio Scientific’s expense

· EuroBio Scientific grants to CareDx the sole and exclusive perpetual right to distribute post-transplant monitoring IVD tests in North

America, including AlloSeq cfDNA, CareDx’s IVD kit version of its market-leading AlloSure dd-cfDNA CLIA test

The company

expects to apply a disciplined approach to capital allocation consistent with its track record. Proceeds from the transaction are expected

to be prioritized toward investments that support CareDx’s long-term growth strategy, including potential inorganic investments

that fit its Precision Diagnostics Solutions model, and may also include the return of capital to shareholders.

The transaction, including the sale of CareDx’s Swedish entity,

requires Swedish regulatory review. The parties anticipate the transaction to close by the end of CareDx’s third quarter, 2026.

Separately, CareDx is providing the following preliminary results for

the first quarter of 2026 in advance of its scheduled quarterly reporting process.

Preliminary First Quarter 2026 Financial Results

· Revenue of approximately $118 million, growth of 39% year-over-year

· Testing Service Volume of approximately 54,900, growth of 17% year–over-year

· Testing Service revenue of approximately $91 million, growth of 48% year–over-year,

· Average revenue per test of approximately $1,660 including approximately $14 million in prior period revenue

· Patient and Digital Solutions revenue of approximately $16 million, growth of 33% year-over-year

· Lab Products revenue of approximately $10 million, decline of 4% year-over-year

· Cash, cash equivalents, and marketable securities of approximately $198 million as of March 31, 2026

The preliminary financial information presented in this press release

is based on CareDx’s current expectations and may be adjusted as a result of, among other things, the completion of customary procedures.

The company anticipates providing further guidance during its first quarter 2026 earnings call on April 28, 2026.
